Question

The area of one end of a U-tube is .1m2 and that of the other end is 10m2 . When a force was applied on the liquid at the first end the force experienced at the other end was 30,000 N. What was the force applied on the liquid at the first end​

Answer 1

Answer:

As we know that pressure head remains constant at a particular horizontal level

A1=0.01m2

A2=1m2

F1=?

P1=P2

F2=20000N

F2F1=A2A1

F1=F2×A2A1=20000×10.01=200N
