A very popular toy on the market several 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 a mass of 50g and is charged with 100g of water. The pressure inside the rocket is 100kPa gage. The exit area is one-tenth of the chamber cross-sectional area. The inside diameter of the rocket is 5cm. Assume that Bernoulli’s equation is valid for the water flow inside the rocket. Neglecting air friction calculate the maximum velocity it will attain.
