Mechanisms of heat transfer

Heat transfer is an essential discipline in thermal engineering that deals with the transfer, conversion, usability, and creation of heat or thermal energy. Transfer of heat occurs through various mechanisms like conduction, convection, radiation, and change of phases. All these mechanisms have distinct characteristics, but these mechanisms can simultaneously occur in an identical system.

You only know one point on a pump curve, where a water pump produces 20 m of hydraulic head at flow rate of 3.67 L/s, and you want to use this to pump water from a lower tank to an upper tank located 15 m higher. Both tanks are open to the atmosphere. Briefly explain your reasoning, in 1‐2 sentences, for each of the following. a) Should this pump be placed next to the lower tank or the higher one? b) Given the data point you have from the pump curve, will the flow rate be higher or lower than 3.67 L/s if the water is pumped exactly 15 m uphill?
A fluid undergoes a frictionless process in a closed system form v1=5ft to v2=2ft^3 in accordance with the relation v=36/(p-8) where p is the psia and v is ft^3. During the process, the fluid rejects 30 BTU/lbm. Compute the change of heat transfer.
Water enters a 5-L tank at a rate of 4.00 kg/s and is withdrawn from the tank at a rate of 6.00 kg/s. The tank is initially four-fifths full. (a) Write a mass balance for this process by assigning a variable function to the mass of water at time t. Describe the terms that are present in the balance; give reasons for deletion of any terms. (b) Solve the balance to find how long it will take the tank to drain completely.
