Question

In the diesel oil transfer facility (ρ rel = 0.85), from the storage tank to the consumption tank, we want to install a pump to circulate a flow of 45 lt / s. The 400m long pipe is cast 150mm in diameter and consists of a check valve, a gate valve and 2 commercial medium radius elbows. The consumption tank is pressurized to 3.8 bar of manometric pressure. Determine the drive power of the pump in kW if its performance is 68%.

Additional data, load loss factors:

1. Check valve Kr = 1.5

2. Gate valve open Kv = 0.21

3. Commercial elbow of mean radius Kc = 0.75, for each elbow

4. Storage tank outlet sharp angles Ks = 0.5

5. Entrance to consumption tank Ke = 1

6. Pipe friction factor f = 0.025
