Question

A and B are at the same elevation of 2.5 m above datum in the valve and pipe line shown in the given figure. Velocity head of 0.5 m, head loss in valve of 0.2 m and pressure head of 2.5 m are the parameters at A. Piezometric head at B is equal to

• A. 5.5 m
• B. 5.3 m
• C. 5.0 m
• D. 4.8 m

Answer 1

The correct option is D 4.8 m

Piezometric head at B

= Pressure head + elevation head

$=(2.5-0.2)+2.5=4.8m$
