Q.1 A horizontal tube of 60 m lenght is connected to a water vessel at one end discharges freely into the surrounding at the other end. For the first 35 m of its length from the vessel, the pipe is 120 mm diameter and its diameter is suddenly enlarged to 280 mm ( K for enlargement = 0.5). The height of water level in the tank is 4 m above the center of the tube. Proposing all losses of head which consider, find the of discharge flow. Take the fanning friction as 0.01 along the tube. If the friction factor is (unknown), suggest the method for evaluate the rate of flow. u= 0.002 Ns'm , and p= 1000 kg/m'.
