A mobile crane was on NAIT main campus (see image below) lifting HVAC units onto the roof of the D-building. The crane has a 100-foot mast actuated by a 10-inch diameter hydraulic cylinder. The mast and cylinder orientation are shown in the schematic (the line of action of the cylinder's extension force acts through point B on the mast). a. For Fjoad = 15 tons what is the required cylinder extension force (Fey)? b. What will the hydraulic fluid pressure [psi] in the cylinder be during extending? 100 feet B 20 feet 15

Problem-5: A Plunger is fitted to a vertical pipe filled with water. The lower end of the pipe is submerged in a sump. If the plunger is drawn up with an acceleration of 5 m/s², find the maximum height above the sump level at which the plunger will work without separation. Assume atmospheric pressure = 10 m water abs, and separation occurs at 2 m water abs. Take acceleration due to gravity as 10 m/s². [Ans. H₂ = 5.33 m]
Diagram of the problem, necessary formulas, clearance and numerical solution It is planned to lift a car with a hydraulic crane. The platform on which the vehicle is is 5,000 cm2 and its mass is 2.5 tons. If the area of the smaller piston is 750 cm2, what must be the force applied to lift the car?
The plunger of the hydraulic lift in a gasoline service station has a diameter of 1 inch. It is operated by a compressed air (density = 63 kg/m3) from the tank in which the pressure is 9.315 x 105 pascals. The output piston and the rack on which the car rests are 2 feet lower than the input plunger and together weigh 1,336.33 newtons. What is the weight of the heaviest car that can be lifted if the output piston has a diameter of 1 foot? Assume 80% efficiency of the machine.

After graduation, you work for a pump manufacturing company. One of your company’s best-selling products is a water pump, which we shall call pump A. Its impeller diameter is DA = 6.0 cm, and its performance data when operating at n. A = 1725 rpm (?A = 180.6 rad/s) are shown in Table.The marketing research department is recommending that the company design a new product, namely, a larger pump (which we shall call pump B) that will be used to pump liquid refrigerant R-134a at room temperature. The pump is to be designed such that its best efficiency point occurs as close as possible to a volume flow rate of V. B = 2400 cm3 /s and at a net head of HB = 450 cm (of R-134a). The chief engineer (your boss) tells you to perform some preliminary analyses using pump scaling laws to determine if a geometrically scaled-up pump could be designed and built to meet the given requirements. (a) Plot the performance curves of pump A in both dimensional and dimensionless form, and identify the best…
1.A vertical cylindrical tank has an orifice for its outlet. When the water surface in the tank is 5 m above the orifice, the surface can be lowered 4 m in 20 minutes, the pressure on the surface being atmospheric. What uniform air pressure must be applied to the surface if the same volume of water is to be discharged in 10 minutes?
