Question 1
A 0.3 m diameter pipe carries oil of specific gravity 0.8 at the rate of 150 l/s and the pressure at the point A is 10 kPa. If the point A is 4 m above the datum line, the total energy at point A closest to
Question 2
For a laminar flow over a flat plate if free stream velocity of fluid is 10m/s. Boundary layer thickness near to wall is 10mm, determine wall shear stress. Take dynamic viscosity as 0.863 Poise. Velocity profile is given by 
Question 3
A nozzle of 7.5 cm exit diameter is fitted in a horizontal pipe of 30 cm diameter. If the flow rate of water through the pipe is 0.3 m3/s, then the force exerted by the fluid on the nozzle in vertical direction will be ____________.
Question 4
A large turbine generates a power of 1000 kW under a head of 50 m. A 1/5th model of a hydraulic turbine is tested against a head of 10 m. The power developed (kW)
Question 5
Oil of viscosity 0.15 Pa.s and specific gravity 0.90, flows through a horizontal pipe of 30 mm diameter .If the pressure drop per meter length of the pipe is 15 kPa, determine the power required per m length of pipe to maintain the flow.
Question 6
A Pelton turbine operates with a jet of 15 cm diameter under a head of 40 m to develop 300 kW at 250 rpm. Given that the coefficient of discharge, speed ratio and mechanical efficiency is 0.98, 0.96 and 0.96 respectively. If the jet ratio greater than or equals to 15, then the number of jets in pelton wheel will be
