6. Determine the pressure difference between the water pipe and the oil pipe shown in the figure below. Draw also the free body diagram or figure of the problem, and your findings after solving it.

QUESTION 18 A 1,200-kg car is resting on a 5.0-m-radius elevating platform of a hydraulic lift. The radius of the input piston is 10 cm. An incompressible fluid fills the volume of the chamber that separates the input piston from the elevating platform. (See the diagram below.) What downward force must be applied at the input piston so that the elevating platform just begins to lift the car? F Fin Input Piston Ain Elevating Platform Aout mg Incompressible Fluid

! Required information An airplane flies on a level path. There is a pressure difference of 514 Pa between the lower and upper surfaces of the wings. The area of each wing surface is about 100 m2. The air moves below the wings at a speed of 80.5 m/s. Estimate the air speed above the wings. Density of air is 1.29 kg/m3. m/s

help If water is moving at 2 m/s in a pipe with a diameter of 0.1 meters, find the speed of the water  when the pipe diameter reduces to 0.05 meters.   Question options:   A)  0.5 m/s   B)  1 m/s   C)  4 m/s   D)  8 m/s

Diagram of the problem, necessary formulas, clearance and numerical solution A boy of mass 45 kg is standing on snow. Calculate the pressure on it if:a) It rests on boots, whose surfaces add up to 500 cm2b) It rests on skis of 130 x 20 cm each. Could you say in which situation it will sink less in the snow? Reason the answer.

Resources A horizontal pipe carries a smoothly flowing liquid of density of 1290 kg/m. At Locations 1 and 2 along the pipe, the diameters are dı = 5.73 cm and d2 = 3.21 cm, respectively. Is the flow speed at Location 2 higher or lower than the flow speed at Location 1? O lower Location 1 Location 2 d2 cannot tell from the data higher The flow speed at Location 1 is 1.13 m/s. What is the pressure difference AP between Location 2 and Location 1 (including its sign)? Ignore viscosity. AP = Pa Is the pressure at Location 2 higher or lower than the pressure at Location 1? higher O cannot tell O lower MacBook Pro 赵
