For the following questions answer them individually
Water at $$20^\circ C$$ is flowing through a 20 cm diameter pipe. Take kinematic viscosity of water at $$20^\circ C = 0.0101$$Â stoke. Assume that the changes from laminar to turbulent at Re = 2320. The critical velocity will be
The speed of an imaginary turbine, identical with the given turbine, which will develop a unit power under unit head, is known as
