For heat exchanger sizing purposes, the cooling water inlet temperature is usually taken as the maximum summer temperature. However, the cooling water outlet temperature can be varied. Theoretically there is an optimum cooling water flow rate (and corresponding cooling water outlet temperature) for each exchanger design. Clearly, there is a maximum...

The first step in preparing a heat exchanger design is assembly of the required data. The minimum requirements for basic data are as follows: Process Fluid Design Flow Rates This is normally the maximum flow rate for the process fluid at full flowsheet rates. However, there may be temporary higher rates during start up or […]

The calculations carried out to design heat exchangers are far from exact. In fact Perry’s refers to the design of heat exchangers as being an art as much as a science. These days almost all heat exchanger designs are carried out using software specifically written for the purpose. The most accepted software used for heat […]
