2.39 A block of mass 10 kg and measuring 250 mm on cach edge is pulled up an inclined surface on which there is a film of SAE 1oW-30 oil at 30'F (the oil film is 0.025 mm thick). Find the steady speed of the block if it is released. Ifa force of 75 Nis applied to pull the block up the incline, find the steady speed of the block. If the force is now applied to push the block down the incline, find the steady speed of the block. Assume the velocity distribution in the oil film is linear. The surface is inclined at an angle of 30 from the horizontal

The pressure intensity at a point in a fluid is given 3.925 N/cm². Find the corresponding height of the fluid when the fluid has specific gravity 1.

Find the fluid force on the side of a tank full of water, where the side is an inverted triangle of height 5 and base 9. The tank is full, so the top of the side has depth 0.

= Water flows into a tank and out through another pipe, as shown in the figure below. The water in the tank has a surface area, Asur f 5.6 m². At the bottom of the tank there is a door inclined at an angle = 25 degrees with respect to the horizontal. The door has a length L = 1.1 m and a width w=1 m (out of the page). The flowrate into the tank is Q₁ (t) flowrate out is Qo(t) = 0.05 m³/s At time t = Asurf = 0.26 m³/s and the 0, the water has a depth ho = 2.5 m. The density of water is p = 1000 kg/m³. Ө h(t) Qout

State Pascal’s principle and give one application of the principle. An object is dropped into a beaker of water. Two forces are operating on the object viz. the weight of object and the buoyant force FB due to the fluid. Explain, in terms of the forces when the object. a.)  Sinks to the bottom of the beaker      b.)Floats in the water A hydraulic press for compacting powdered samples has a large cylinder with a diameter of 10.0 cm and a small cylinder of diameter 2.0 cm. If a force of 350 N is applied to the small cylinder, what will be the force exerted by the fluid on the large cylinder? Be consistent with your units.

Please I want answer for this question - 2 . Many Thanks

36. Find the fluid force on the vertical side of the tank, where the dimensions are given in feet. Assume that the tank is full of water. Note: The density of water is 62.4 lbs per cubic foot.
