Question

True or False

1. For a fluid flowing through a bend in a pipe, calculating the force exerted by the fluid on the bend requires knowing the pressure distribution over the entire interior of the bend.

2. The force of the weight of a fluid on a pipe bend can be neglected from the resultant force calculation if the bend is in the horizontal plane.

3. When an abrupt axisymmetric enlargement occurs in a horizontal pipe, the impulse-momentum equation can be used to calculate the reduction in the pressure and velocity head.

Explanation / Answer

1) False

When fluid is passing through the pipe having constant area of cross section then that fluid exerts constant amount of pressure on walls of pipes and having constant velocity depending upon what Amount of pressure is applied on fluid from its starting point to make it move.

2)True

To obtain a reasonable first approximation , these volumes can be neglected

3)true
