2. From the figure shown, the tank contains oil having s specific gravity of 0.82. Oil flows at a certain rate which produces power in the jet equal to 9hp. Diameter of orifice is 80mm with Cy = 0.96 and Cc= 0.62. Air oil, s = 0.80 2.80 m

In a hydraulic press, the ram has a diameter of 20 cm and the plunger 2 cm. The fluid  is an oil of specific gravity 0.8. Calculate the mass that can be raised by placing a  mass of 100 kg on the plunger:  (i)When the plunger and the ram are on the same horizontal plane, and  (ii)When the liquid level in the plunger is 0.5 m above that in the ram.   What is the mechanical advantage of the press in cases (i) and (ii) above?

In the figure shown, solve for the theoretical velocity of the jet, theactual velocity and the discharge through the orifice considering thefollowing:a) p1 = p2 = 0 Cc = 1.00 (rounded)h = 5 m of oil Cv = 0.97Do = 5 cmb) p1 = p2 = 0 Cc = 0.62 (sharp-edged)h = 5 m of water Cv = 0.98Do = 5 cmc) p1 = 70 kPa C = Cv = 0.95 (rounded)p2 = 0 Do = 7.5 cmh = 1.60 m (liquid with sp. gr. = 3)
