Question

Three charges -0.02micro coulomb and +0.02 micro.Coulomb and 0.04 micro coulomb are placed at the vertices of a triangle 10cm then potential energy of system is

Answer 1

In order to estimate the frictional head loss in a pipe 1 m in diameter, through

which castor oil of specific gravity 0.96 and dynamic viscosity 9.9 poise, is to

be transported at the rate of 5000 litres per second, a test was conducted on

a pipe of diameter 50 mm using water at 15°C as the model fluid. Calculate

the discharge required for the model pipe.
