At what maximum speed does a compressed air torpedo move, which expells 18 kg of air every second at a speed of 118 m/s? The force of water resistance is proportional to the square of the velocity and is equal to 480 N at a speed of 21 m/s. (The solutiom is 44 m/s)
To determine the frictional stress exerted by fluid on a smooth wall, velocities v, and v2are measured in the turbulent zone at distances y, and y2 from the wall. Derive an expression forthe frictional stress in terms of the four measured quanities and the fluid density.
A hydroelectric power plant uses Pelton-type turbines, in which multiple nozzles are used to accelerate the waterwhich is directed onto the turbine blades, which are exposed to an atmospheric pressure of 101.325 kPa. The water enters the nozzles with an absolute pressure of 500 kPa and a speed of 5 m/s, and the nozzle outlets are exposed to atmospheric pressure and have an internal diameter of 5 cm. Consider that the specific mass of water is 1,000 kg/m3. Determine the mass flow rate of water through each of the nozzles, and explain why the actual mass flow rate will be lower.
The weight of a thin flat plate 50 cm * 50 cmin size is balanced by a counterweight that has a mass of2 kg. Now a fan is turned on,and air at 1 atm and 25°C flows downward over bothsurfaces of the plate (front and back in the sketch) with afree-stream velocity of 10 m/s. Determine the mass of thecounterweight that needs to be added in order to balancethe plate in this case.
A U-tube open at both ends is partially filled with water. Oil having a density of 750 kg/m3 is then poured into the right arm and forms a column L = 10.00 cm high. The density of air is 1.29 kg/m3.The right arm is then shielded from any air motion while air is blown across the top of the left arm until the surfaces of the two liquids are at the same height. (d) Determine the pressure difference between the water and oil columns(e) Determine the speed of the air being blown across the left arm.
What are the two mechanisms theoretically considered in turbulent flow?
The 1.5-in (0.125-ft) gap between two large plane surfaces is filled with SAE-30 oil at 80 °F (μ=0.0063 lb.s/ft2). What force is required to drag a very thin plate of 5-ft2 area between the surfaces at a speed of 0.5 ft/s if this plate is equally spaced between the two surfaces.
It is proposed to meet the water needs of a recreational vehicle (RV) by installing a 3-m-long, 0.5-m-diameter cylindrical tank on top of the vehicle. Determine the additional power requirement of the RV at a speed of 80 km/h when the tank is installed such that its circular surfaces face (a) the front and back (as sketched) and (b) the sides of the RV. Assume atmospheric conditions are 87 kPa and 20°C.
What is turbulent viscosity? What causes it?
At what speed will the torpedo cavitate when running at a depth of 12 m? and At what depth should it be to avoid cavitation at 25.5 m/s?
A paratrooper and his 7-m-diameter parachute weigh 1200 N. Taking the average air density to be 1.2 kg/m3, determine the terminal velocity of the paratrooper.
Consider an air solar collector that is 1 m wide and 5 m long and has a constant spacing of 3 cm between the glass cover and the collector plate as shown in Figure below, Air flows at an average temperature of 45°C at a rate of 0.15 m/s through the 1-m-wide edge of the collector along the 5-m-long passageway. Disregarding the entrance and roughness effects and the 90° bend, determine the pressure drop in the collector.
