Aheat pump receives energy from a source at 75 °c and delivers energy to a boiler that operates at 300 kpa. the boiler input is saturated liquid water and the exit is saturated vapor both at 350 kpa. the heat pump is driven by a 3 mw motor and has a cop that is 50% of a carnot heat pump cop, what is the maximum mass flow rate of water the system can deliver?

Select any two (2) areas of applications of chain-drive. (clo4) a)-permanent lubrication necessary b)-hydraulic forklift truck operation c)-rigging and heavy moving materials d)-relatively high maintenance costs e)-costlier than belt drives

Acertain flow of air (at stp) has a velocity distribution given by v i (in ft/s). if this flow is going through a 4 ft square area in the yz-plane (centered at the origin), what is the mass flow rate (in lbm/s)?

Atank with constant volume contains 2.27 kg of a mixture of water phases (liquid-vapor). in the initial state the temperature and the quality are 127 °c and 0.6, respectively. the mixture is heated until the temperature of 160 oc is reached. illustrate the process in a t-v diagram. then, determine (1) the mass of the vapor in kg at the initial state, (2) the final pressure in kpa.
