Answer / Solution

UNSOLVED

Water flows past a horizontal plate of area 1.2m². If the velocity gradient and coefficient of viscosity adjacent to the plate are 10s^-1 and 1.3x10^-5Nsm^-2 respectively, calculate the force acting on the plate.

Answer / Solution

A horizontal pipe of cross – sectional area 1.2cm² has one section of crsoo sectional area 5cm². If water flows through the pipe , and the pressure difference between the two sections in 300 Pa, how many cubic meters of water will flow out of the pipe in 1 minute?

Answer / Solution

UNSOLVED

1. state Bernoulli`s theorem for the horizontal flow.
2. On which principle does the Bernoulli`s theorem based?

Answer / Solution

UNSOLVED

A pipe is running full of water . At a certain point A, it tapers from 30cm diameter to 10cm diameter at B, the pressure difference between point A and B is 100cm of water column. FInd the rate of flow of water through the pipe.
