Question

A 5 cm diameter jet of water is moving with a velocity of 50 m/s. Strikes a
series of curved vanes and making an angle of 30o with the horizontal. If the
absolute velocity at exit is 0.9 of that at inlet and make an angle of 120o with
the direction of vane motion, calculate (a) speed of the vanes so that the
efficiency will be maximum (b) work done/sec. (c) efficiency. (d) vane
angles at inlet and outlet.

Answer 1

Answer:

Let's say Nathan and Carl are playing dice. They roll one die; if it comes up "6," Nathan pays Carl $5, and if it comes up anything but "6," Carl pays Nathan $1. Let's say they play 11 times.
