A vertical gap of 0.1 mm contains a fluid of viscosity (2 Pa.s). A thin metallic plate sheet (0.2 m x 0.3 m) is to be lifted up with a constant velocity of 0.1 m/s through the gap. Find the force (f) given the weight of the plate is 60 N a) If the plate is in the middle of the gap b) If the plate is as shown below 4f

A door in the side of a tank is 20cm wide and 30cm high. If the tank is filled with oil r.d. 0.82 to the top of the door what is the force exerted on the door and the position of its line of action How much oil will have to be drained out for the force to be 40N and what will be the position of the new line of action

(Just Question a.) A water filled pipe has water flowing at v1= 5.90 m/s in a section of pipe where the diameter is d1= 20.2 cm and the pressure is known to be P1= 7.00×104 N/m2 above atmospheric pressure.     If the pipe carries the water 3.5 meters up hill without any change in diameter, what is the new absolute pressure within the pipe? After flowing up the hill described above, the pipe narrows to 80% of its original radius, what will be the new water velocity (v2) in the pipe? What will be the absolute pressure (P3) in the smaller pipe?   a. What is the volume flow rate through the smaller pipe?
