Chapter 11, Problem 11.78P
Consider the Rankine cycle of Problem 11.77, whichrejects 2.3 MW to the condenser, which is suppliedwith a cooling water flow rate of 70 kg/s at 15°C.
(a) Calculate UA, a parameter that is indicative of thesize of the condenser required for this operatingcondition.
(b) Consider now the situation where the overall heat transfer coefficient for the condenser, U, is
reduced by 10% because of fouling. Determinethe reduction in the thermal efficiency of thecycle caused by fouling, assuming that the cooling water flow rate and water temperature remainthe same and that the condenser is operated at thesame steam pressure.

A horizontal shell-and-tube condenser is to be used to condense saturated ammonia vapor at l 45 lbf/in2 .abs (Th = 82°F), The condenser has 19 steel tubes (1.5-in. OD, 1.3-in. ID) 14 ft long through which cooling water is flowing. The tubes are arranged hexagonally on 2-in. centers. The latent heat of ammonia at these conditions may be taken as 500 Btu/lb. The cooling water enters at 70°F. Determine the capacity of the condenser for these conditions.
With sketches, distinguish between parallel and counterflow heat
exchangers. Why is the counterflow heat exchanger configuration
preferred over the parallel type?
Saturated steam at 110°C is condensed in a shell-and-tube heat exchanger (1 shell pass; 2, 4, ⋯ tube passes) with a UA value of 2.5 kW/K. Cooling water enters at 40°C.
(a) Calculate the cooling water flow rate required to maintain a heat rate of 150 kW.
(b) Assuming that UA is independent of flow rate, calculate and plot the water flow rate required to provide heat rates over the range from 130 to 160 kW. Comment on the validity of your assumption.
