Q- voltage source of 12v is driving the circuit.if circut
draw the current of 0.5A them source voltage will became
11.8v.what is the power dilevered by source when circuit
draw 5A current ?

Answer Posted / badshah hussain rizvi

internal resistance is .4ohm.hence poewer loss is 10watt.so
net power delivered is 50 watts.

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
