Q1. (Reading: Çengel and Boles, Thermodynamics: An Engineering Approach, 8th Ed., Pages 307-311) The amount of energy waste by a refrigerator increases by a number of malpractices. For example; opening the refrigerator door frequently will increase energy waste as the warmer air outside replaces the cool air inside. It is also not recommended to place the hot foods into the refrigerator before cooling them to the room temperature. Imagine a typical household refrigerator with an internal temperature of 4 °C. The refrigerator has a coefficient of performance of 1.4. The internal dimensions of this refrigerator are 186 cm (height) x 84 cm (width) x 75 cm (depth). The half of the refrigerator volume is used for storing food items. The air filling the other half of the refrigator volume contains 0.004 kg moisture/kg air on average. While the moisture content of the air in the kitchen is 0.01 kg/kg air, the temperature and pressure in the kitchen are 23°C and 97 kPa, respectively. Assuming…
Q3. The data listed in the following table gives hourly measurements of heat flux q (cal/cm? /h) at the surface of a solar collector. As an architectural engineer, you must estimate the total heat absorbed by a 150,000-cm2 collector panel during a 14-h period. The panel has an absorption efficiency eab of 45%. The total heat absorbed is given by: h = eab q A where A = area and g = heat flux. 4 6. 10 12 14 0.10 5.32 7.80 8.00 8.03 6.27 3.54 0.20
Air treated as an ideal gas and having a specific heat at constant volume Cv=1200 j/kg.K undergoes a process. During this process, heat is observed to exit the system with an amount of 10 kJ while work is provided to the system with an amount of 23 kJ. If the initial temperature of air was 20 C, what is the final temperature of air if the mass of air undergoing the process is 0.3 Kg. Select one: O a. 59.5 C O b. 48.73 C O c. 63.4 C O d. 56.1 C
Q1/ The air circulation in a large room by using fan (10 hp). Assuming a well-insulated, sealed room determine the internal energy increase after (1 h) of operation.
An air bubble rises from the bottom of a well where the temperature is 25oC, to the surface where the temperature is 27o If the depth of the well is 5m and the atmospheric pressure is 101.325kPa, determine the following: Initial pressure inside the air bubble (P1). Volume of air bubble at state 1. Volume of air bubble at state 2. Percent increase in volume of the bubble.
Steam generators are a type of heat exchanges that are used in power plants to generate steam at desired pressure and temperature (Fig. Q1.b). In a steam generator, saturated liquid water at 30°C enters a 60-mm diameter tube at the volume flow rate of 12 L/s. After exchanging heat with hot gas, the water changes to steam and leaves the generator at a pressure of 9 MPa and a temperature of 400°C. During this process, the diameter of the water/steam tube does not change.(i) Calculate the steam mass flow rate.
