1.An incompressible fluid flows horizontally in the x-y plane with a velocity given by v = 20 (z/h)^(1/3),where z and h are in meters and h is a constant.
Determine the average velocity for the portion of the flow between z= 0 and z=h. Answer is between 10 and 20 m/s
Plot a graph showing the discarge per unit width per unit width q for various depths if the specific energy remains constant at this value. What will be the depth when the discharge is 1/3 of the discharge at critical depth
The cycle has a thermal efficiency of 35%, and steam changes from saturated vapor at 300 C during the heat addition process. If the mass flow rate of the steam is 2kg/s, determine the net power (kw) output of this engine.
