Web11 mrt. 2024 · A and C are stable because as the temperature increases from this point, the rate of heat generation is less than the rate of heat removal. This means that as the temperature increases, heat is removed faster than it is generated so the temperature will be brought back down to that operating point. WebA minimum flow through the pump must be maintained to prevent flashing within the casings. The heat transferred from the motor must be removed to keep the fluid below its saturation temperature at the actual pressure. If 15 oF is accepted as a temperature rise in the pump casing - the minimum water flow through the pump can be estimated to lighthouse marina fox lake
