In any centrifugal pump the difference between the amount
horse power put into the pump shaft by the driver and the
amount delivered by the pump is absorbed in the pump in the
form of heat.This difference is greatest at low capacities
and makes it necessary on multistage unit to provide for a
minimum flow through the pump to carry of excess heat and
prevent overheating and flashing of the liquid in the
pump.minimum flow is best insured by a by-pass installed
between the pump discharge and the first valve and connected
back to the source of suction supply.This bypass may be
manually or automatically operated,but it is highly
important that the line be open during periods of light load

Let’s say we live in a country that gets very cold, in Northern America / Europe. In winter, we monitor the ouside temperature, so that heaters can be switched on, inside the house. The idea is that, the colder it is outside, the warmer it should be inside. The heating side of things is just a heater that is either switched on, or switched off. Just from the information that has been given, please discuss this matter in depth. Provide reference to OPEN / CLOSED loop control, FEEDFORWARD / FEEDBACK control and MODULATING / ON_OFF control raised in the discussion.
