Q. A pulley 18 in diameter is free to rotate about a horizontal axle. A 220 mass and a 420 mass are tied to either end of a massless string, and the string is hung over the pulley.
Q. Water at ground level is moving at a speed of 1.20 m/sec in a pipe at a pressure of 850 kPa. The pipe goes up to the fourth floor of a building where its elevation is 12.5 meters above the ground and its radius is the same. The density of water is 1000 kg/ m3. What is the pressure of the water on the fourth floor?
