In the unsteady state heat transfer experiment, why is the heated water temperature limited to 85-90 Celsius degrees in the unsteady state heat transfer experiment? Select one: O a. Type K thermocouples attached to the apparatus will not give accurate readings for temperatures higher than 90 Celsius degrees. O b. Water below 80 Celsius degrees will not heat the specimens. Oc. Water above this temperature tends to boil, inducing cavitation in the pump. Od. Water above this temperature will cause severe burns if touched.

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.

a. An air stream passing through a 2-inch (1/6 ft) diameter, thin-walled tube is to be heated by high- pressure steam condensing on the outer surface of the tube at 320 °F. The overall heat transfer coefficient, h between steam and air can be assumed to be 25 Btu/(ft2.hr °F) with the air entering at 100 ft/sec, 10 psia, 40 °F. The air is to be heated to 150 °F. Determine the tube length required. Assuming Rayleigh Line flow, calculate the static pressure change due to heat addition. Also, for the same inlet conditions, calculate the pressure drop due to friction, assuming Fanno flow in the duct with f = 0.018. b. c. d. To obtain an approximation to the overall pressure drop in this heat exchanger, add the two results. Discuss the accuracy of this calculation.

A 0.6 m tank contains saturated liquid water at 200 °C. A valve in the bottom of the tank is opened and half the liquid is drained. Heat is transferred from a 300 °C source to maintain constant temperature inside the tank.
