Twenty degree C air enters a tube bank which is to be used to remove 150 [kW] of heat from condensing refrigerant. The refrigerant is flowing inside the tubes of the bank and causes the external tube surfaces to be maintained at 100o C. The air is accelerated by a fan to 8 [m/s] upstream of the bank. The bank is to be constructed of transverse rows of fifty 8 [mm] O. D. tubes 0.75 [m] wide with the center-to-center transverse spacing equal to 15 [mm].

Calculate the exit temperature of the air from the bank

Water is the working fluid in an ideal Rankine cycle. The pressure and temperature at the turbine inlet are 1200 lbf / in^2 and 1100°F, respectively, and the condenser pressure is 140 lbf/in^2 The mass flow rate of steam entering the turbine is 1.4 x 10^6 lb/h. The cooling water experiences a temperature increase from 60 to 80°F, with negligible pressure drop, as it passes through the condenser. Determine for the cycle:

(a) the net power developed, in Btu/h

(b) the thermal efficiency.

(c) the mass flow rate of cooling water, in lb/h.
