Homework 1 Problem 6: Pressure cookers use water at very high pressures to cook food very quickly. They have been around for more than 300 years, although their use has strongly declined in recent years (early models had a nasty habit of exploding). a) How much force, in newtons, must the latches holding the lid onto a pressure cooker be able to withstand if the circular lid is 25.5 cm in diameter and the gauge pressure inside is 1.05 atm? Neglect the weight of the lid. F = ______

Problem6 When a viscous fluid flows parallel to a horizontal plate, it leads to the development of a thin boundary layer on the plate surface. The velocity within the boundary layer varies with the vertical direction as u(y) = US where 8(x) = 3.5 VX/Uis the boundary layer thickness vx 8(x) that increases with the horizontal position. Outside of the boundary layer, the flow is uniform and equal to the free stream velocity U... Show that for two fluids of different viscosities (₁, ₂) and densities (P₁, P2) and flowing at the same free stream velocity, the ratio of the drag force they generate on the plate is proportional to the square root of the ratio of the viscosities and densities: FD2 FD1 = H₂P2 M₁P₁
