Fluid Mechanics studies the response of fluids on forces exerted on them.

Video description:
This video shows a simplified derivation of the energy equation for fluid flow. It also shows the difference between the energy equation and Bernoulli Equation.

A sample problem is also solved:
A pipe 50 cm in diameter carries water at a rate of 0.5 m3/s. A pump in the pipe is used to move the water from an elevation of 30 m to 40 m. The pressure at section 1 is 70 kPa gage and the pressure at section 2 is 350 kPa gage. What power in kilowatts and in horsepower must be supplied to the flow by the pump? Assume hL = 3 m of water and α1 = α2 = 1.
