A popular toy on the market some years ago was the water rocket. Water (at 10°C) was loaded into a plastic rocket and pressurized with a hand pump. The rocket was released and would travel a considerable distance in the air. Assume that a water rocket has mass of 50 g and is charged with 100 g of water. The pressure inside the rocket is 100 kPa gage. The exit area is one-tenth of the chamber cross-sectional area The inside diameter of the rocket is 5 cm. Assume that Bernoulli equation is valid for the water flow inside the rocket. Neglecting air friction, calculate the maximum velocity the rocket will attain.
In whole analog to the work energy theorem for the translator motion, it might be stated for rotational motion as: Δ W rot = K rot The net rotational work given by the force
