Two pipes A and B are connected in parallel between two points. Pipe A is 200 m long and has a diameter of 16 cm, pipe B is 150 m long and has a diameter of 12 cm. Both the pipes have the same friction factor of 0.018. A partially closed valve in pipe 'A' causes the discharge in the two pipes to be the same. All other minor losses can be neglected. The value of the valve coefficient is - Valve F = 0.018 L=200m, d-16cm L,=150m, d=12cm B F = 0.018
