Max likes to drink tea. He uses his kettle to heat 1.6 liters of water from 18°C to 100°C every day. What does it cost him to heat the water per year (365 days) if he pays 29 cents per kWh of electricity. State the costs in euros to two decimal places. The material values of water averaged for the swept temperature range are: Cwater=4.18 kJ/(kg-K); pwater=983 kg/m3; Awater=0.654 W/(m2. K); nwater=467-10-6 kg/(m-s).

As he rides the train to work on a - 4ºC winter day, Mr. Trump notices that he can hear the click ofthe train going over the spaces between the rails. Six months later, on a 30ºC summer day, the railsare pushed together and he hears no clicks. If the rails are 5 meters long when the temperature is30ºC, how large a gap is left between the steel rails (α steel = 1.2 x 10 - 5 ºC -1 ) on the cold winter day?

In a company there are the following consumptions for energy and energetics. The company works 8hours a day and consumes an average of 10 kWh/day of electrical energy, its thermal energy production system(heating) works through the combustion of a gas that provides 111.76 kcal/h for each gram that isgas flaring, using an average of 0.25 lbm/h of gas.Fuel is also used in another thermal system that on average consumes 1 lbm/h, whose density is 1.1g/mL with calorific value of 1193.45 BTU/lbm. If the average costs for energy and energy are of$0.20/kcal. Determine the total cost of energy and energy for each work week (6 days per week).week)
In the United States, energy for household heating is generally sold using English units, e.g., therm, gal, and cord. A house in Wisconsin uses 1200 therms of thermal energy during the heating season. Calculate the cost of fuel if the furnace uses (a) natural gas with an efficiency of 70%; (b) No. 2 fuel oil, efficiency 65%; (c) kerosene, efficiency 99.9% (unvented); and (d) wood with l5% moisture with an efficiency of 50%. Use the data in Tables 2.2, 2.7, and 2.13. The efficiencies are based on the HHV. Assume the cost of natural gas is $8/MBtu, the cost of No. 2 fuel oil is $3/gal, the cost of kerosene is $3.50/gal, and the cost of wood is $100/cord. Assume the bulk density of cord wood is 30 lbm/ft3 .

What does it mean for an engineering device that has steady-flow? (choose 3 answers) 1- it has been operating for a long time. 2- the properties do not change with time. 3- the property values can be different at different location in the device. 4- the total energy content in the control volume remains unchanged. 5- the rate of energy coming into the system equals to the rate of energy exits the system.
A group of athletes were tested for isometric endurance by measuring the length of time they could resist a load pulling on their legs while seated. The approximate amount of time (called the holding time) that they could resist the load was given by the formula t = 31,293w^-1.5, where w is the weight of the load in pounds and the holding time t is measured in seconds. a. Determine the holding time for a load of 29 lb. b. When the weight of the load is tripled, by what factor is the holding time changed?
