Determine variable pressure drop....pressur edrop do to control valve?

Question

Basically designing an olefins plants...lots of distillation towers and pumps...need to determine the pressure drop of control valves.

Told 30-60% of variable pressure drop = control valve pressure drop
Also Variable pressure drop is NOT..... ro*g*h

So i was told though that is the defintion of variable pressure drop.....not sure what to use

thanks

Answer 1

I hope these help.

Answer 2

Neither wat or wats is contained in the dictionary. yet in case you meant "what's the adaptation between a stress regulator valve and a stress administration balue, the stress regulator value is one to regulate stress at a particular aspect, which contain utilized via organic gasoline supliers to diminish gasoline less than severe stress, to a secure, consistent stress entering your position, even as a stress administration valve is one which controls stress toa certain aspect, and if the stress exceeds that aspect, it opens and releases theexcessive stress, utilized in warm water warmers to avert it from exploding if the thermastat sticks, and the temperture rises previous boiling aspect, ensuing in steam which could reason very severe pressures straight away. yet another simular valve is the single way valve to avert movemient of liquid contained in the incorrect direction. All are for protection criteria, and are required via progression codes.
