A liquid is flowing through a horizontal straight pipe at 4.57m/s. The pipe used is commercial steel with diameter of 4cm. The viscocity of the liquid is 4.46cP and the density is 801kg/m3. Calculate the friction loss in J/kg for a 36.6m section of the pipe. HOMEWORK 1. Water is to flow through a horizontal commercial steel pipe having a length of 305m at the rate of 0.00946m3/s. A head of water of 6.1m is available to overcome the friction loss, hf. Calculate the pipe diameter. 2. 0.015m3/s of acetic acid is pumped through a 75mm diameter horizontal pipe 70 m long. What is the pressure drop in the pipe? Viscosity of acid is 2.5mNs/m2, density of acid is 1060kg/m3, and roughness of pipe surface is 6105m
