Question

1-An object floats with half its volume beneath the surface ofthe water. The weight of the displaced water is 921 N. What is theweight of the object?
Weight of object in N? 2- A 17000 N vehicle is to be lifted by a 21 cm diameterhydraulic piston. What force needs to be applied to a 7.9 cmdiameter piston to accomplish this?
Minimum force needed on small piston? Units 3-Water flows through a horizontal pipe of cross-sectionalarea 2.6 cm2 at a pressure of 8.1 atm. The flow rate is1.7 x 10-3 m3/s. At a valve, the effectivecross-sectional area of the pipe is reduced to 1.4 cm2.What is the pressure (in atm) at the valve?

Explanation / Answer

given that Fout= 17000N diameter = 21cm = 0.21m radius = d/2 = 0.21/2 = 0.11m area of  out piston = r2= 3.14 * (0.11m)2 = 0.037m2 area of in side piston = r2 = 3.14 (0.0395m)2 = 0.0048m2 Fin = Ain/Aout *Fout plug in values F = ------N please post remaing posts seconed time. thank you. plug in values F = ------N please post remaing posts seconed time. thank you.
