A schematic of a homemade hydraulic jack is shown in the figure below, with cylindrical tube ends of different radii, r, = 0.0520 m and r, = 0.200 m, respectively. F A A2 (a) If a downward force of F, = 12.0 N is applied to the end with the smaller radius, how much force F, would the jack exert on a car if it were sitting above the other end? (Enter the magnitude.) (b) If the smaller piston is pushed down a distance d, = 0.176 m, through what distance d, would the other end move? m

Water from a pipe is coming at a rate of 100 liters per minute. If the radius of the pipe is 5 cm, the Reynolds number for the flow is of the order of (density of water 3 1000kg/m V coefficient of viscosity of water = 1mPa s)

Calculate the weight (lbs) of a solid steel roller bar. It is 14.0 in. long and 3.0 in. in diameter. Use the density of steel ≈ 0.2833 lb/cu in. (Round to the nearest hundredth.)?

The vertical face of a dam across a river has the shape of a parabola 20 m across the top and 10 m deep at the centre. Set up an integral representing the force that the river exerts on the dam if the water level is 6 m above the lowest point of the dam. There is no need to find the value of the force, only the set up of the integral is required, however, all the details are expected.

DEL STAT PRGM TAN Name Fluid Dynamics HW 5. A garden hose is held above ground so that the stream of water from it starts horizontally (see the figure below). The cross sectional area of the hose end is 2 cm- and the stream of water hits the ground 3 m away. 3 m (a) If the end of the hose is 1.4 m above the ground determine the velocity at which the water stream leaves the end of the pipe. [5.61 m/s) (b) The cross sectional area of the end of the hose is now reduced to 1 cm by placing a thumb over it. Assuming that the rate of flow is not affected, determine how far the stream of water will hit the ground. [6.0 m)

A schematic of a homemade hydraulic jack is shown in the figure below, with cylindrical tube ends of different radii, 1 = 0.0480 m and r2 = 0.300 m, respectively. (a) If a downward force of F1 = 16.0 N is applied to the end with the smaller radius, how much force F2 would the jack exert on a car if it were sitting above the other end? (Enter the magnitude.) ]N (b) If the smaller piston is pushed down a distance d, = 0.176 m, through what distance d, would the other end move? m

Two circular platforms are attached to a fluid reservoir.  On one platform rests the entire cast of Glee frozen in carbonite.   A force of 7.0 N is applied downward to the empty platform with radius 8.0 m.  The other platform applies a force of 7.2 N to the carbonite-frozen pop-idols.   What is the radius of the platform holding the Glee cast?

(a) What is the pressure drop (in N/m2) due to the Bernoulli effect as water goes into a 2.50 cm diameter nozzle from a 8.70 cm diameter fire hose while carrying a flow of 38.0 L/s?  N/m2 (b) To what maximum height (in m) above the nozzle can this water rise? (The actual height will be significantly smaller due to air resistance.)  m

A slab of ice floats on a freshwater lake. What minimum volume must the slab have for a 45.0 kgkg woman to be able to stand on it without getting her feet wet? Express your answer with the appropriate units.

Adump truck uses a hydraulic cylinder, as the drawing illustrates. When activated by the operator, a pump injects hydraulic oil inte the cylinder at an absolute pressure of 2.67× 10“ Pa and drives the output plunger, which has a radius of 0.110m. Assuming the plunger remains perpendicular to the floor of the load bed, find the torque that the plunger creates about the axis identified in the drawing.
