Q) Compare the heat transfer coefficients under the following conditions (Assume flow is turbulent). (1) Two fold increase in the diameter of the tube; the flow velocity is maintained constant by a change in the rate of liquid flow. (2) Two fold increase in the flow velocity by varying the mass flow rate. Comment on. the results.
The condenser of a large thermal power plant consists of a single body with two passes each and 30000 pipes.It is a shell and tube type heat exchanger. Pipes are 25 mm inner diameter, thin-walled and steam,11000 W / m2With a convection coefficient of .K, it condenses on the outer surfaces of the pipe. HeatThe transfer required by the exchanger is 2000 MW, and 30000 kg / h of water will be transferred from the pipes.as with flowing flow rate. Water enters at a temperature of 20 ° C, steam at 50 ° C.is condensing. Calculation temperature of the cooling water from the condenser? Required per passdetermine the pipe length?
