Water at a pressure of 200 kPa at street level flows into a house building at a velocity of 0.86 m/s through a pipe of 2.7 cm inside diameter. However, the pipe's inside diameter reduces to 1.2 cm on the second floor, which is located at a height of 9 m. The density of water is 1000 kg/m' and the gravity, g is 9.81 m/s. By neglecting all energy losses, (a) Calculate the velocity of water on the second floor. (b) Estimate the pressure of water on the second floor.
