Questions
A horizontal pipe of non-uniform cross-section allows water to flow through it with a velocity1 when pressure is 50 kPa at a point. If the velocity of flow has to be 2 at some other point, the pressure at that point should be
detailed solution
Correct option is C
According to Bernoulli’s equation for horizontal pipe,P1+12ρv12=P2+12ρv22⇒ P1+12ρv12−v22=P2⇒ P2=50×103+12×103×12−22⇒ P2=50×103−1.5×103=48.5 kPaTalk to our academic expert!
