The internal pressure, to which a water supply pipe is subjected to, is
  • a)
    full hydrostatic pressure when water in the pipe is at rest
  • b)
    pressure head and velocity head in the pipe, when flow at full velocity is taking place 
  • c)
    a + water hammer pressure
  • d)
    b + water hammer pressure
Correct answer is option 'C'. Can you explain this answer?

The internal pressure within a pipe is caused by the water head to which the pipe can be subjected and the additional transient pressures. The maximum internal pressure under worst circumstances is sum of full static pressure and the water hammer pressure.

Internal Pressure in Water Supply Pipe

Internal pressure in a water supply pipe refers to the pressure that is exerted on the pipe from the inside due to the flow of water. It is important to understand the type of pressure that is exerted on the pipe as it can affect the durability and strength of the pipe. The internal pressure can be classified into different types based on the flow of water.

Full Hydrostatic Pressure

Full hydrostatic pressure is the pressure that is exerted on the pipe when the water in the pipe is at rest. It is equal to the weight of the water column above the pipe. It is a static pressure and does not change with the flow of water.

Pressure Head and Velocity Head

Pressure head and velocity head are the components of the total head of the flowing water. Pressure head is the pressure that is exerted on the water due to the weight of the water column above it. Velocity head is the pressure that is exerted on the water due to its velocity. When the water is flowing at full velocity, both pressure head and velocity head are present.

Water Hammer Pressure

Water hammer pressure is a sudden pressure surge that occurs in the water supply pipe due to the sudden change in the flow of water. It occurs when a valve is closed suddenly, causing the water to stop flowing abruptly. This sudden stoppage of water causes a pressure surge that can damage the pipe and the fittings.

Conclusion

The correct answer to the given question is option C, which is water hammer pressure. The internal pressure in a water supply pipe can be classified into different types based on the flow of water. It is important to understand the type of pressure to ensure the durability and strength of the pipe.
