Q1. A 200mm diameter pipeline divides into two smaller pipelines, one being 100mm in diameter and the other being 150mm in diameter. If the velocity in the 100mm pipe is 0.3m/s and that in the 150mm is 0.6m/s, calculate the flowrate in litres/s and the velocity in m/s in the 200mm pipe. [ 13 l/s, 0.413m/s] Solution: Flow Rate = (pi/4)(0.1)2(0.3) + (pi/4)(0.15)2(0.6) = 0.01296 cubicmeters/sec = 12.96 l/sec. (ans.). Velocity = (Flow Rate)/(Area) = [0.01296]/[(pi/4)(0.1)2] = 0.4125 m/s. Q2. If the specific volume of water is 0.001251 m3 /kg. calculate:
