A jet of water (20◦C) impinges on a turbine blade that is translating at constant velocityU= 5 m/s. The velocity of the jet relative to the fixed nozzle of 12 cm2cross section isVj= 25 m/s. The blade turns the jet so that it makes an angleθ= 150◦measured counterclockwise from the positive x-axis. Taking into account the weight of the 150 N blade, butneglecting the weight of water on the blade, calculate:
(a) the horizontal and
(b) vertical components of force required to maintain constant blade speed.

An important dimensionless parameter concerned with very high-speed flow is the mach number, defined as v/c, where v is the speed of the object such as an airplane or projectile, and c is the speed of sound in the fluid surrounding the object. for a projectile traveling at 1170 mph through air at 50 ˚f and standard atmospheric pressure, what is the value of the mach number?
