- cuboid object made of iron (density 7.7x10^3 kg/m^3) ( 1 cm on each side) when placed in a container filled with water and mercury. Object floating between layer of water and mercury as in the figure fine how long this object has suck into the mercury. if water have a density 10^3 kg/m^3 and mercury have a density 13.6x10^3 kg/m^3A hollow cylinder 80 cm long in diameter, one end closed, is immersed vertically with its closed end being held 7.50 m below the water surface. The cylinder is at first full of water, but compressed air is admitted from beneath in the immersed position until it has displaced two thirds of water. Patm-101.5 kPa. Find the total absolute pressure of air in the cylinder kPa. 7.5 m 0.8 m 0.6 0.3 Do not write the unit. You will only input the numerical answer in the space provided. Unit of the Correct Answer: kPa abs Decimal Places required in the final answer: 3Open tank (4.5 m long, 2.5 m height and 3 m wide) contains liquid (S-0.75) to height 1. m. If this tank is accelerated along its length on a horizontal truck at a constant value of 3.5 m/s, determine pressure at the bottom of the tank at front and rear edges (in kN/m). (take y=9.8 kN/m for water)
- 5. What is the pressure at the bottom of the 7.5 m tall storage tank of fluid at 25°C? Assume that the fluid is gasoline with atmospheric pressure 101 kPa on the top surface. Repeat the question for the liquid refrigerant R- 134a when the top surface pressure is 1 MPa.

The gate is parabolic as sketched, looking straight at the gateThe water level in the 1.8 m high and 1 m diameter cylindrical tank in the figure is 1.4 m. If this tank is rotated around its own axis at what speed will the axial depth be zero? (In other words, what is the number of revolutions at which a dry area will begin to form at the bottom of the tank?) Take the gravitational acceleration as 10 m / s2 and π as 3.Plz answer I will rate !:) A right circular cylindrical tank with its circular base on the ground is full of water. The diameter of the base is 4m and the height of the tank is 4m. Set up a Riemann sum to approximate the hydro static force against the lateral wall of the tank. Then express the force as an integral and evaluate it.
