- The height of a cylindrical tank, containing 15 lb of gas at 70psia and 115°F, is triple its diameter; the constant R=45ft-lb/lb°R,Find the tank dimensions in feet.arrow_forward2- a. A U tube differential manometer containing mercury was used to measure the difference of pressures in two pipes containing water. The difference in mercury level is 0.9 m, the level of water in left limb from mercury level to center of the left pipe is 1.8 m and the level of water in right limb from mercury level to center of the left pipe is 0.8 m. Find the head difference in m. S for water = 1, S for mercury 13.6. b. Draw a neat diagram shows all parameters. c. Discuss the differences between U tube and slanted U tube manometers. (sub divisions b and c, upload the document) Difference in heads in marrow_forwardQ3. Figure 1 shows a load of mass 10 kg situated on a piston of diameter D, =100 mm. The piston rides on a reservoir of oil of depth h, = 40 mm and specific gravity S= 0.9. The reservoir is connected to a round tube of diameter D, = 5 mm and oil rises in the tube to height h,. Assuming that the oil in the tube is open to atmosphere and neglecting the mass of the piston, find h,.arrow_forward

- A cylindrical tank is fully filled with water . In order to increase the flow from the tank, an additional pressure is applied to the water surface by a compressor. For P0 = 0, P0 = 5 bar, and P0 = 10 bar, calculate the hydrostatic force on the surface A exerted by water.arrow_forwardThe hydraulic jack in the figure is used to lift a 1000 kg mass load to a height y2 = 150 mm. The diameter of the lift cylinder is D = 50 mm. With this information, analyze the system and determine. a) The pressure, in bar.b) The diameter d of the hand pump cylinder, so that the driving force F1 is 50 N. c) If the maximum displacement of the pump pistonfor y1 = 20 mm, how many drives will it take to fully lift the load? d) If you want to reduce the number of actuations by 2/3, keeping the diameter of the lift cylinder, D, the same actuation force F1, and the stroke y1, what geometric changes can be made in the system?arrow_forwardAn air bubble increases from the bottom of a well where the temperature is 27°C, to the surface where the temperature is 29°C.
