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…

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…

2. In studying for your CBEMS 125B exam, you get hungry and decide to boil some water in a pot to make instant noodles. You put your aluminum spoon, with a long handle (i.e. good to use "long fin approximation"), in the pot in anticipation of stirring the noodles into the boiling water. However, your phone rings, and you leave the spoon in the boiling water on the stove for quite a while (i.e. the system reaches steady-state conditions) before you come back to it. The boiling water is at 100°C and room temperature is 25°C. The spoon has a square handle that is 0.6 cm per side. At a handle height of 8 cm, the temperature of the long aluminum spoon is 62°C. The Royal Society for the Prevention of Accidents lists a maximum surface temperature of 58°C as a "safe" touchable temperature for metals. Is the spoon safe to pick up at a handle height of 12 cm? Justify your answer with calculations. Assume (1) No radiation effect, (2) convection heat transfer coefficient is uniform in the pot…

Solve question 2 based on the answer of question 1.  You have a natural gas furnace in your home that used 78,500 cubic feet of natural gas for heating last winter. Your neighbor has a furnace that burns heating oil and used 516 gallons of heating oil last winter. You can convert the natural gas and heating oil consumption data into Btu to determine which home used more energy for heating. Natural gas BTU:  1,028 Btu per cubic foot Oil BTU: 138,590 Btu per gallon   Natural Gas BTU= 80,698,000  Oil BTU                = 71,512,440    The home that used a natural gas furnace used more energy for heating. 2.- You need a new furnace for your home, and you are comparing systems that use natural gas and heating oil. One factor to consider is the cost of the fuel. You can compare the price of the fuels on an equal basis by dividing the price per unit of the fuels by the Btu content per unit of the fuels to get a price per million Btu. Assume Natural gas price = $10.50 per thousand cubic…

LESSON: ZEROTH LAW OF THERMODYNAMICS AND TEMPERATURE MEASUREMENTMODIFIED TRUE or FALSE Directions: Write TRUE if the statement is correct, otherwise, change the underlined word/s or values to make the statement correct. Write your answer on the space provided before each item number. Statement: The Philippine one-peso coin has a diameter of 23.0 mm at 25 room temperature. Assume that the coin is made up of steel.14. The increase in coin’s diameter when placed in boiling water is 0.0207 mm.15. The final length of coin when placed in boiling water is 23.207 mm.16. If the coin is heated at 42 degrees Celsius, then the increase in diameter is 0.0207 mm.17. If the initial temperature is doubled, then the increase in coin’s diameter when placed in boiling water is 0.0414 mm.

Are you as strong as a horse? Purpose: To understand the concept of work and power and to calculate the power generated by yourself or a friend. Materials: A tape measure, stairs, and a stopwatch, cell phone, or wristwatch. Key Physics Concept: Power is the rate of doing work. Power can be calculated by dividing the work done by the time it takes to do the work; in this case we will do work against gravity on a stair case (you may add your power in doing pushups to test your arm power). Can you guess what your peak horsepower is? You may do the stairs one at at time or multiple stairs at a a time; whatever is most safe and efficient for you. Procedure: Observations: Analysis: Conclusions: Application: 1. Will your hp change if you performed the activity for a longer duration (for example, climbed the CN tower staircase)? In what way? Explain. 2. Research the horsepower generated by a car. How does the average person's peak power rating compare to it? How many average people would it…

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.

SUBJECT: PHYSICS

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.
