Answer Posted / naveed ahmad
In controller must be used proportaional (P). according to
change in input it 'll change the output. means output is
proportional to the input. if controller is direct action
it 'll be directly proportional and if controller is
reverse action then it 'll be inverslly proportional. Keep
in your mind controller input is always an error signal.

Calculate the maximum pressure drop that can be allowed to occur across a control valve, so that we can prevent cavitation / flashing from occurring. Use the following formula: Δ P allow = Km (P1 – PvapourA) where, Δ P allow - the maximum allowable differential pressure for sizing purposes, or terminal pressure drop; Km- the valve recovery coefficient from the manufacturer’s catalogue; P1 - absolute inlet fluid pressure; PvapourA - absolute fluid vapour pressure at the inlet temperature; Use Atmospheric pressure = 101.3 kPa, P1 = 1200 kPa(g), PvapourA = 4 kPa, KM = 0.72
