Question #3 Consider the flow around the Quonset hut to be represented by superimposing a uniform flow and a doublet. The flow is steady, incompressible, and irrotational. The ground plane is represented by the plane of symmetry and the hut by the upper half of the cylinder. The free-stream velocity is 175 km/h; the radius Ro of the hut is 6 m. The door is not sealed, and the static pressure inside the hut is equal to that on the outer surface of the hut, where the door is located. If the door to the hut is located at the ground what is the net lift acting on the hut? What is the lift coefficient? Door = 175 h km Ro %3D

At 20°C, the viscosity of water is 1.0x10-3 Pa-s and the viscosity of molasses is 51 Pa-s. Consider two tubes of the same length L, with fixed pressure difference Ap across each pipe. If water flows through Pipe 1 and molasses flows through Pipe 2, and both have the same flow rate Q, what is the ratio of the radius of Pipe 2 to Pipe 1?

Q. 26. A cylindrical tank having radius R is half filled with water having density p. There is a hole at the top of the tank. The tank is moved horizontally, perpendicular to its length, with a constant acceleration equal to the acceleration due to gravity (g). Find the maximum pressure exerted by water at any point on the tank. Atmospheric pressure is Po. Assume that there is no spillage.
