A shell-and-tube process heater is to be selected to heat water (Cp = 4190 J/kg°C) from 20 °C to 90 °Cby steam flowing on the shell side. The heat transfer load of the heater is 600 kW. If the inner diameterof the tubes is 1 cm and the velocity of water is not to exceed 3 m/s, determine how many tubes needto be used in the heat exchanger.
5000 kg of dry air per hour is cooled from 60 oC to 34 oC in a countercurrent heat exchanger. In the cooling process, the cold air supplied to the heat exchanger is used at a speed of 6200 kg/h and at 20 oC. If the same amount of hot air was cooled from 60 oC to 24 oC in a longer heat exchanger with the help of cold air under the same conditions, determine what the ratio of the new heat exchanger length to the original heat exchanger length would be (assume the specific heat of the air is constant).
