Pumping Power Calculation for Oil Transfer

What is the pumping power required to transfer oil from a storage tank to an overhead tank?

Given data: Oil specific gravity 0.8, pumping rate 30 m3/s, datum difference 5m, suction velocity 1 m/s, discharge velocity 6 m/s, pump efficiency 80%.

Pumping Power Calculation:

Let's calculate the pumping power required to transfer oil from the storage tank to the overhead tank.

To determine the pumping power needed, we first consider the potential energy difference, kinetic energy difference, and flow work. The pump efficiency is also taken into account.

By substituting the given values into the equations, we can calculate the power required:

  • Potential energy difference = g * h (where g = 9.8 m/s^2 and h = 5 m)
  • Kinetic energy difference = 0.5 * (6^2 - 1^2)
  • Flow work = 1 * g * h * (0.8 * 1000 kg/m^3)
  • Total energy difference per unit mass = Potential energy difference + Kinetic energy difference + Flow work
  • Pumping Power = (Total energy difference per unit mass * pump rate) / pump efficiency

Calculate the values and find out the pumping power required to transfer the oil efficiently.
