The velocity of flow of water in a pipe of 150 mm dia is 0.3m/sec, a diaphragm with a central hole 80mm in diameter is placed in the pipe obstructing the flow. With coefficient of contraction $$C_c = 0.60, the loss of head from Vena Contracta to a point downstream will be

A

0.1083m

B

0.2250m

C

1.2054m

D

0.8250m
