Question

(a) State and prove Bernoulli's theorem for the streamlined flow of an ideal fluid.
b) A horizontal pipe line carries
water in a streamline flow. At a point along the pipe
where the cross sectional area is 10 cm2, the water velocity is 1 m/s and the
pressure is 2000 Pa. What is the pressure at another point where the cross sectional
area is 5 cm2?

​

Answer 1

Answer:

a. According to Bernolli's theorem the sum potential, kinetic and pressure energy remains constant
