About this course
Chemical engineers always deal with pumps in different projects. This is because pumps have been the heart of any plant to transfer fluid through the process at the required flow rate and pressure.
That’s why it is always important for a process engineer to understand how to specify the required process parameters to operate the pump properly and how the pump performance is affected by changes in process conditions or fluid physical properties.
In any project, pump hydraulic calculations form one of the main activities that a process engineer carries out. In addition, he should be able to read the pump curve and predict the effect of process changes on the pump operation. He should choose the correct control method and configuration of the pump.
