Gate Fluid Mechanics Questions
5. A centrifugal pump operates at a speed of 1500 rpm and delivers a flow rate of 500 L/min. If the pump efficiency is 80%, calculate the power developed by the pump. (Take the density of the fluid as 1000 kg/m³ and acceleration due to gravity as 9.81 m/s²)
**Solution:**
Given, Pump efficiency (η) = 80%
Flow rate (Q) = 500 L/min = 0.5 m³/min
Density (ρ) = 1000 kg/m³
Acceleration due to gravity (g) = 9.81 m/s²
Power (P) = (ρ * g * Q * H) / η
Where H is the head developed by the pump.
6. Draw a schematic diagram of a centrifugal pump and label its main components.
7. A centrifugal pump is required to lift water from a sump at a depth of 5 meters and deliver it to a tank located at a height of 15 meters. Calculate the total head developed by the pump.
**Solution:**
Total head (H) = Suction head + Delivery head
Suction head = 5 meters
Delivery head = 15 meters
Total head = 5 + 15 = 20 meters
