A container contains 2.5 ft^3 of water at 40 °C and ambient pressure is heated until its specific weight becomes 61 lb/ft^3. Find the percentage of weight that must be discharged to keep its original volume.

B2. An oil of specific gravity 0.74 is flowing through the pipe of diameter 30cm. one end of the simple U tube manometer contains mercury, is inserted with the center of pipe and other end is open to atmosphere. The level difference in mercury is found in the left limb as 30 cm. The distance between the center of the pipe and the mercury level is 14 cm. Find the pressure of oil in the pipe in kPa. Draw the diagram neatly. The pressure of oil in the pipe (in kPa)

Find the gauge pressure at the bottom of a swimming pool that is 12 ft deep in psi. (The mass density of water is 62.4 lb/ft^3).

Find the surface tension in N/m in a soap bubble of 30 mm diameter when the inside pressure is 1.962 Pa above the atmosphere.

A force sensor is immersed in a iquid with a density of 61 lb/ to a depth of 42 in and then placed  in a second liquid with a density of 732 N/. What is the change in force on the sender if the diameter of the sensor is 8 cm and the change in depth is 5.9 cm?

if air is at pressure of 2200 lb/ft^3, and at a temperature of 800°R, what is the specific volume?

A 1.7 ft3 rigid vessel contains 2 lbs of water at 400F. What is the pressure in the vessel?

Two pipes A & B carries an oil of specific gravities 0.9 & 1.2 respectively. The center of the pipe A is 60 cm above the pipe B. The height of oil in right limb is 50 cm. Also, the mercury level difference is found in right limb as 50 cm. Find the pressure difference between these two pipes in kPa. Also find the pressure equivalent in water head in mm. The difference of pressure between two pipes (PA- PB) (Unit is in kPa) = Equivalent to Water head in mm =
