- An open rectangular tank 3.8m high, 2.5m wide and 6m long is filled with water at a depth of 2.2m. If it is accelerated at 2.3 m/s^2 and is moving at a plane inclined 15 degrees from the horizontal, determine the following: a. acceleration of the vessel along the horizontal; and b. angle of fluid inclination. Note: Use density of water as 1000kg/m3 and specific weight as 9.81kN/m3.Water at 15 °C flows through a nozzle that contracts from a diameter of 10 cm to 2.5 cm. The exit speed is v2 = 20 m/s, and atmospheric pressure prevails at the exit of the jet. Calculate the force required to hold the nozzle stationary. Neglect weight. Calculate the pressure at section 1. Neglect weight.1. The head of water at the inlet of a pipe 2000 m long and 500 mm diameter is 60 m. A nozzle of diameter 100 mm at its outlet is fitted to the pipe. a) Determine the velocity of water at the outlet of the nozzle if friction coefficient for the pipe is 0.01.

- An oil flow rate of 0.012 m³/s is required in an industrial process. The flow system includes a pressure tank pushing the oil through 200 m of new ductile iron pipe (DIP: 15 cm diameter, square-edged entrance) to point "2" (atmospheric pressure) as shown in Figure P3.11.11. The sur face of the fluid in the tank (point "1") is at elevation 100 m and the end of the pipe (point "2") is at elevation 106 m. What air pressure will be needed over the fluid to produce the requisite flow? (S.G. (oil) = 0.84, v 2.03 x 106 m²/s, and e = 0.00012 m.)A vertical cylindrical tank with diameter 2 m and height 5 meter is full of water. How much work is required to pump all the water to the top of the tank? Use 1000 kg / m3 for the density of water and 9.8 m /s2 for the acceleration due to gravity. (Volume of a cylinder: v =pir^2h )Consider a rectangular plate of width B = 1m (measured in the direction normal to the plane of this sheet) and negligible thickness, which separates two fluids of densities ρ and ρw. A mass of density ρs is supported by an inextensible rope that passes through a pulley connected to one end of the plate. Consider that ρ = 1.59ρw and ρs = 2.40ρw, where ρw = 1000 kg/m3. Determine the volume that this mass must have for the system to remain in equilibrium, as shown in the figure.
