An air-cooled window DX unit is used for space cooling. The unit has a capacity of 4.5 tons and has a SEER of 15. If the unit operates for 2204 hours during the summer, how many kWh of electricity will be used? Hint: In the U.S., the SEER is the ratio of cooling in British thermal units (BTUs) to the electrical energy consumed in watt-hours. You may need to convert the unit in this process.

On a cold winter day, you turn up the thermostat in your house. Assume that your house is well sealed and that no air enters or leaves the house. When the air temperature in your house rises a short while later, what statement is correct regarding the air pressure? Question 10 options: The air pressure does not change at the higher temperature. The air pressure increases at first but then decreases again as the temperature approaches its higher value. The air pressure is lower at the higher temperature. The air pressure decreases at first but then increases again as the temperature approaches its lower value. The air pressure is higher at the higher temperature.
Which of the following thermocouples can measure temperature in a comparatively high range? 1) iron-constantan 2) chromel-alumel 3) platinum-rhodium 4) iridium-rhodium
Hello Sir,Good Morning.I have a question in my homework related thermodynamics lesson. The following below is my question. Please advice. Thank you. Regards,Irfan An air conditioning system is used to keep the house at 65°F when the outside temperature is 85°F. The house gets heat through the walls and windows at a rate of 810 Btu/min, and the rate of heat generation inside the house from occupants, lights, and equipment is 120 Btu/min. Determine the minimum power input required for this air conditioning system.
Problem 3 - Flame Manufacturing is designing a large pressure vessel that contains boiling water (pwater = 850 kg/m³) with a volume of 185 m³. If the cooling system for the pressure vessel fails the pressure-operated relief valves (PORVS) will open and emit steam (Psteam = 35 kg/m³). The change from water to steam is a result of the depressurization of the vessel. If the steam exits the pressure vessel through a 40-mm-diameter pipe determine the following: (a) symbolic equation (no numbers used, just symbols) for the time needed for all the water to escape; and (b) the time in hours for the water to escape if the exit steam velocity is 400 m/sec. Flame Manufacturing needs this data to guarantee the safe operation of the pressure vessel. The two provided densities are sufficient to generate the final solution. Define all the symbols used. ▬▬▬

This causes a small piece of material, such as cotton, in the cylinder to burn. A fire syringe has a cylinder with an initial volume of 10.0 cm, an initial pressure of 1.0 atm, and an initial temperature of 300. K. The piston is pushed down, which decreases the volume to 1.0 cm and increases the temperature to 510. K. Which of the following indicates the final pressure inside the cylinder and helps explain the pressure? The pressure decreases to 0.41 atm; the gas particles in the cylinder hit the walls of the cylinder with less speed. B The pressure remains constant at 1.0 atm; the changes in volume and temperature cancel each other ot. The pressure increases to 5.9 atm; the gas particles in the cylinder hit the walls of the cylinder with greater speed. D The pressure increases to 17 atm; the gas particles in the cylinder hit the walls of…
