Apelton wheel operates from a net head of h 300 m and at a flow rate of 4.2 m /s. the wheel diameter is 1.5 m. and the rotational speed is 450 rpm. the water that leaves the penstock is divided into 5 streams. the nozzle coefficient is cn 0.98 for each nozzle. impulse blades turn the flow into the direction b2 25, and as a result of friction, the relative velocity reduces by an amount that gives a velocity coefficient cy 0.90. find (a) work output of the turbine, (b) the hydraulic efficiency, (c) the nozzle diameter and the number of buckets in the wheel.

W= fd
where f is an applied force and d is the distance over which it is applied. when a parachuting skydiver is at constant velocity, he is experiencing "terminal velocity", the point at which his acceleration down is canceled out by air resistance. that means that the resisting force of the air is equal to his weight, but in the opposite direction. with this, we can solve for the work done by the force.
w = fd
w = (92.0)(9.81 m/s^2) (325)
w= 2.93 x 10^5 j
the value for work in this case is positive because it is pushing up on the skydiver, who has a downward force of gravity.
therefore the answer is 2.93 x 10^5 j

Hey did u get the answer?

330 wpu is be the right temperature

Answer is  true.  because the sensory memory it can also have a fraction of a second before the information is lost. hope it .
