Task 2 The transfer of heat from one fluid to another is an essential component of all chemical processes. Whether it is to cool down a chemical after it has been formed during an exothermic reaction, or to heat components before starting a reaction to make a final product, the thermal processing operation is core to the chemical process. It is essential that heat transfer systems for chemical processes are designed to maximize efficiency. Because the heat transfer step in many chemical processes is energy intensive, a failure to focus on efficiency can drive up costs unnecessarily. Task expected from student: a) Compare the basic design between the classifications of heat exchanger equipment's (Any three HE equipment's). b) Summarize the merits, demerits, limitations and applications of heat exchanger equipment's with neat sketch.

Directions: Answer the questions after each situation. 1. David Aquino, engineering director, started out the day uptight. His young child had the flu the night before, and he had been up all night to help. Upon arrival at his office, David had to make urgent phone calls to approve a two-week overtime work plan due to a plant fire the night before and to plan for a product committee meeting the next day to counter environmental concerns about a wastewater treatment plant. Then he spent 30 minutes reviewing the qualifications of new candidates and decided on one. He asked for salary information and wanted to examine the offer before it was sent. He asked for further justification for the budget requested by industrial engineering for a minicomputer. Without reading it, he approved the research proposal from material engineering. He rejected an invitation to speak at a regional meeting of the Philippine Society of Mechanical Engineers by giving an untrue reason. David made a note for the…

You are assigned as the head of the engineering team to work on selecting the right-sized blower that will go on your new line of hybrid vehicles.The fan circulates the warm air on the inside of the windshield to stop condensation of water vapor and allow for maximum visibility during wintertime (see images). You have been provided with some info. and are asked to pick from the bottom table, the right model number(s) that will satisfy the requirement. Your car is equipped with a fan blower setting that allow you to choose between speeds 0, 1,2 and 3. Variation of the convection heat transfer coefficient is dependent upon multiple factors, including the size and the blower configuration.You can only use the following parameters:

Jasim Review/Recap Sheet Q1- Answer with true or false and rewrite the false statements completely in correct form, otherwise no mark will be put on the false statements. 1 2 To represent a location on earth surface you need to define its altitude and longitude angles. 3 Solar zenith and solar incidence angles have the same value for horizontal surface. At sunset time the value of solar altitude angle is maximum. 4 The angle which represents the inclination of a given surface is the zenith angle 5 6 7 8 When the absolute value of sun-wall azimuth angle exceeds 90' this means that the sun rays are reaching the receiving plane. The solar irradiance and the solar irradiation have the same physical meaning. In the case of clear sky weather, the beam solar irradiation on a horizontal surface is less than the diffused irradiation. The total solar radiation received by a tilted surface is the same as that…

hints: The flask will be filled with water (at a constant rate of 500 gallons per minute). It will take me exactly 10 minutes to escape from the chains. The diameter of the tank at 1 foot intervals. I am 5 feet 9 inches tall, and I'm pretty skinny so that you can ignore both my volume and the volume of the stool in your analysis. A gallon is equal to 0.13368 cubic feet.  You can think of the volume and the height of the water as functions of time. You can easily find an expression for V (t), and then use your expression for volume in terms of height to solve for h(t). after 10 minutes amount of water in the tank=66.84 ft3 t=69.3 minutes h(t)=e66.84t/100?  -1 h(10)=e66.84(10)/100?  -1=7.39 ft  Height of stool=1.64 ft Height of water in the tank=7.39 ft Questions: show work How fast is the water rising?  I would like to know how long I will have to hold my breath during the last part of the stunt.

Four months into a six month deployment, you are a solo pilot returning to home base after an uneventful overwatch mission to a non-disclosed desert location. Your mission was extended 90 minutes requiring at least one additional aerial refuel. The moon has now set. A shift in prevailing winds causes an infrequently used runway to be active. You are less familiar with the approach to this runway and have only used it during VFR conditions. The instrument approach plate reveals you will fly a prolonged DME arc taking you out over the unlit desert away from the dimly lit base. While flying the above instrument approach, you take another look at the approach plate. When you look up again the airfield lights are visible through the upper portion of your canopy. You did not sense any change in your aircraft attitude. Which of the following best describes what happened while you looked at the approach plate? OA. The black hole effect has amplified the normal reflection of the airfield lights…

HELLO, CAN U HELP ME TO MY RESEARCH PART?, MY RESEARCH PART IS DATA GATHERING PROCEDURE, AND I'LL SEND THE SAMPLE THAT MY TEACHER GAVE ME, THIS IS MY TITLE BTW " Students who play Axie Infinity as scholars do not make enough money to support their studies: a qualitative study of Axie Infinity scholars among the students of Precious High Academy" THANKS!

(assume certain values which are not provided to you ) The class includes 40 people. Heat loss from the walls of the class, including the glass windows, is negligible. A flow of cold air enters the classroom via the main entrance, flows in the classroom, and then leaves through an emergency exit door located at the back of the class. Both the entrance door and the emergency exit door have the same dimensions of 1.2 m length and 1.9 m height. Assuming steady-state heat transfer upon reaching the room temperature at a constant value: a-If cold air enters the room at 20 °C, the heat generated due to themetabolism of a student/lecturer is 70 W, and air flow rate through bothdoors is 0.05 m/s, determine the room temperature. Assume that thechanges in properties of air during the increase in room temperature maybe safely ignored. b-Why is volume not necessary to solve part (a)

Task 1: Consider a simplified shape of a blood vein branching- similar to the Brachial vein. You like to determine whether this person is having a hypertension (high blood pressure) or a hypotension by determining the pressure in the main vein. Note that a nominal value for the normal pressure for that specific vein is 140 mmHg. If the found value is higher, we can consider the person to be hypertensive. Assume a blood density of 1050 [kg/m³] and a viscosity of 3.5 [Pa.s] Is this a hypertension case? (i.e., is the pressure in the main vein P1 > 140 mmHg? What is the classification of the flow in the main vein, rı = 7.5 mm? (laminar or turbulent)? Show your work. P3 =l.5KPA G=4 mm そ:004 % ri=7.5 mm 2= 3 mm *= 0.02

task 4 please

Pls.answer thank you! A classroom that normally contains 40 people is to be air-conditioned with window air-conditioning units of 5 KW cooling capacity. A person at rest may be assumed to dissipate heat at a rate of about 360 KJ/hr. There are 10 light bulbs in the room, each with a rating of 100 watts. The rate of heat transfer to the classroom through the walls and the windows is estimated to be 15,000 KJ/hr. If the room air is to be maintained at a constant temperature of 21°C, determine the number of window air-conditioning units required.
