Find the flow (per foot in the Z direction) through each side of the square with the corners at(0,0), (0,1), (1,1), (1,0), due to: V = (16y-12x)i + (12y - 9x) j and how that continuity is satisfied. The answer in the book is: YES (please show detail) Thank you, Lisa. ISBN: 0070625379

Francis turbine

(See attached file for full problem description)

A tank of demensions: L=4m, H=3m, W=3m is filled up to 2m with an oil (Sp=.83). The tank is closed except fpr a small vent at the upper right corner. This tank is then accellerated to the right at an uniform acceleration of 19.62 m/s^2.

Find the the point of maximun pressure, the value of this pressure. Show all work in detail.

Flow around a circular cylinder

The maximum flow past a circular cylinder is 2 X the Up stream velocity. The max velocity occurs at the center line of the top of the cylinder. Assume std pressure and Temp for air and irrotational flow. What is the difference between the lowest and highest pressures? The cylinder is suspended in a 40/m wind.
