3.9 A float value of "the ball-cock" type is required to close an opening of a supply pipe feeding a cistern. The value should close down when 60% 15 mm diam. Float Hinge 150 of the volume of the spherical float is immersed in water. 500 mm The valve has a diameter of 15 mm and the fulcrum of the operating lever is to be 150 mm from the value and 0.50 m from the center of the float. Determine the minimum diameter of the float if it is required to close the valve against a pressure of 147 kN/m² gauge. Neglect the weight of the lever and the float.

A tank open to the atmosphere contains oil of sp. gr. = 0.80, gasoline sp.gr. =0.90 and seawater sp.gr. = 1.03. If the depths of the liquids are 0.65 m., 0.92 m., and 1.15 m. for oil, gasoline and sea water respectively. Find the absolute pressure at a depth of 2 m.
QV: a hydraulic press is used to compact powdered samples. The device is made of two interconnected cylindrical chambers filled with oil if density psubscripto anc closed by two pistons. The small chamber on the right has diameter d and the large chamber on the left has diameter 5d. A lever is attached to the piston pushing down on the fluid in the small cylinder. The horizontal lever is hinged on the left, at distance L from the small piston, and a force of magnitude Fsubscript0 is applied vertically down at distance 2L from the hinge (Fig.5). You may assume that the lever and pistons have negligible mass. a. Determine the magnitude of the force Fin that the small piston exerts on the fluid in the small cylinder. Hint: you may consider that the lever is at rest in the horizontal position. b. Determine the pressure change applied to the fluid by the small piston. c. Determine the magnitude Fout of the force that the fluid applies to the large piston.
