Question

Can anyone do this ? 1. 60°C water is pumped from a tank. What is the maximum height that the pump can be installed? The friction loss in the suction line is 2.2 J/kg. The vapour pressure of 60°C water is 19.93 kN/m2. The NPSHR of the pump is 4.0 m.

Answer 1

The max height is approximately 4.106 m

Step-by-step explanation:

The given parameters are

The friction loss = 2.2 J/kg

The vapor pressure = 19.93 kN/m²

NPSHR = 4.0 m

We have;

4 × 997 × 9.8 = P + 101,325 - 2.2J/kg × 997 kg/m³ - 19930

P = 4 × 997 × 9.8 - (101,325 - 2193.4 - 19930) = -40119.2

P = -40119.2

h = 40119.2/(997 × 9.8) ≈ 4.106

The max height ≈ 4.106 m
