There are two pumps the primary and the secondary pump. The primary is the chilled water pump which is what pumps cold water throughout the building and the secondary circulates the water.

just multiply pump capacity by 3
As the chilled water system is a close system and basically consist of two loops i.e one loop from pump discharge to load & second loop from load to pump suction.Now,the effect of pressure drop will be more prominent in the second loop ,after the flow exit the load.Hence we have to alleviate the pressure where the effect of pressure loss & small water requirement is more prominent and i.e the suction side of the pump.
A water well switch controls the pump that draws water from a well. It turns the pump on when water is needed and off when the desired water level is reached. This switch is crucial for the efficient operation of a water well system, ensuring that the pump runs only when necessary, saving energy and preventing damage to the pump from running dry.

You are probably referring to Absorption refrigeration. Try Google.
A turbine pump is nothing but a centrifugal pump. It is used for pumping water from deep water bodies to water distribution systems. Please see related link for detailed description and its operation.

Chilled water flow in gpm x difference in chilled water temperature/24
A chiller system uses heat to create chilled water by transferring heat from the water to a refrigerant, which then circulates to reject the heat to the outside environment. The chilled water is then used for air conditioning or refrigeration purposes.
