Answer Posted / mohammad iftikhar
firstly u need to convert the following parametrs
1- conver inlet pressure into PSIG, your outlet pressure
2- you need to know what is your temperature max & min
3- you must know your flow rate
4- diffrential pressure
5- nominal pize size
6- sizing for ....mean for which fluid
