1.	A pump works on the principle of centrifugal theory, running at 900 rpm is working against a head of 16 m. The external diameter of the impeller is 360 mm and the outlet width is 40 mm. If the vane angle at the outlet is 30°and the manometric efficiency is 80%, the discharge of the pump will be:
A.	0.22 m3/s
B.	0.24 m3/s
C.	0.18 m3/s
D.	0.14 m3/s
