Centrifugal pumps are widely used in various industries for fluid transportation. Understanding the principles and operation of centrifugal pumps is crucial for engineers and technicians working in the field of fluid mechanics and hydraulics. To test your knowledge and enhance your understanding of centrifugal pumps, here are some gate questions on centrifugal pump along with detailed solutions.
A centrifugal pump delivers water at the rate of 0.22 m 3 /s from a reservoir at ground level to another reservoir at a height \(H\), through a vertical pipe of 0.2 m diameter. Both the reservoirs are open to atmosphere.

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

2. Pump Disassembly This stage will vary the most from one pump to another. Many centrifugal pumps use a back pull out design where the pump can be removed from the casing once spacers and bolts are removed. The mechanical seals can be accessed in these pumps without removing the casing from the inlet and outlet pipes.
