Saturated steam at 77°C and 1.8kg/s flow rate is desired to be condensed in a water-cooled condenser. The features of the condenser are as follows:
Two-pipe pass-through shell-and-tube heat exchanger
Condensation takes place on the body side.
There are 150 brass pipes (one pipe makes two passes), ( D_{o} = 19mm, D_{l} = 15mmand k pring =50 w mK )
The coolant is moving inside the pipes at a speed of 1.5m/s.
Cooling water enters the heat exchanger at 25°C.
Body side convection coefficient is 5411.54 W / (m^2) * K' *
a) Pipe side convection coefficient
b) Find the heat exchanger length. Specify the length by drawing a figure.
