This resource, from Mathematics for Engineering Exemplars, shows the application of mathematics when designing a pumping system. The operating pressure of a pumping system can vary due to various factors, so all the relevant operating conditions need to be assessed to ensure the selected pump is capable of achieving the entire operating range.

Pumping the water up only 10 m (33 feet), for example by raising the water from a river to the top of a nearby riverbank, requires 1,000 joules (1 Btu) of energy. For continuous flows, it is more useful to look at the power required for pumping, which is the energy required over time:

Example - Horsepower Required to Pump Water. 20 gallons of water per minute is elevated 20 ft. The horsepower required (ex. friction loss in piping and efficiency = 1.0) can be calculated as. Pwhp = (20 gpm) (20 ft) (1) / (3960 (1.0)) = 0.10 hp. Power required to pump water at 60oF with ideal pump efficiency 1.0: Power Required to Pump Water ...

The pressure of the pump in psi must be greater than the backpressure of the water column in the pipe. As an example, if your water depth was 231 feet down and your pump was 10 feet below the water level, the total head pressure pushing against the pump would be 231 feet or 100psi (2.31feet of head {of water} = 1psi).

Nov 15, 2011 The idea for pumped hydro storage is that we can pump a mass of water up into a reservoir (shelf), and later retrieve this energy at will—barring evaporative loss. Pumps and turbines (often implemented as the same physical unit, actually) can be something like 90% efficient, so the round-trip storage comes at only modest cost.

This natural movement of fresh water towards the sea prevents salt water from entering freshwater coastal aquifers (Barlow, 2003). Groundwater pumping/development can decrease the amount of fresh water flowing towards the coastal discharge areas, allowing salt water to be drawn into the fresh water zones of coastal aquifers.
