shell-and-tube heat exchanger

A shell-and-tube heat exchanger with one shell pass and two tube passes employs condensing steam at 1 atm on the shell side to heat 10 kg/s of engine oil from 50 to 60?C in the tubes. The steam enters as saturated vapor and leaves as saturated liquid with hag =2.26 MJ/kg. The hot condensate leaving the exchanger is subsequently used to heat water to 60?C in another shell-and-tube exchanger, with the condensate occupying the shell side and the cooler water flowing in the tubes. The cool water enters at 20?C. Using approximate values of U from Table 10-1, or your own calculations, determine the size of the steam condenser and suggest sizes for the exchanger that serves as the water heater. For each exchanger suggested, indicate the amount of water that may be heated. As an alternative, suggest a single choice for the heat exchanger that employs throttling of the water flow. Comment on the suggested arrangements.
