Asmall water pump is used in an irrigation system. the pump takes water in from a river at 10oc, 100 kpa at a rate of 5 kg/s. the exit line enters a pipe that goes up to an elevation 20 m above the pump and river, where the water runs into an open channel. assume the process is adiabatic and that the water stays at 10oc. find the minimum pump power required.

0.98kW

Explanation:

The conservation of energy is given by the following equation,

Where

Mass flow

Specific Enthalpy (IN)

Specific Enthalpy (OUT)

Gravity

Heigth state (In, OUT)

Velocity (In, Out)

Our values are given by,

For this problem we know that as pressure, temperature as velocity remains constant, then

Then we have that our equation now is,

jupiter

explanation:

it is so massive and has such a strong gravitational pull its likely prevented the formation of a planet between itself and mars in the asteroid belt
