Consider the steady, incompressible flow of depth h of a liquid
of known density ρ and unknown viscosity µ down a flat plate as
shown in Figure 1. Air is the fluid above the liquid layer. The
force of gravity is in the vertical direction with acceleration g,
and the plate is at an angle θ with respect to the horizontal.
Assuming the coordinate system as shown, with x aligned with the
flow direction, and y normal to the plate,...

Starting with this equation dP/ dy = ρg (1) and this relationship P/ Po = ρ/ ρo (2) where Po and ρo are pressure and density at sea level. Assume g is constant and y = 0 at sea level. (a) Determine the variation in pressure in the earth’s atmosphere as a function of elevation y above the sea level. (b) At what elevation is the air pressure equal to half the pressure at sea level?

Suppose that a liquid has an appreciable compresibility. Its density therefore varies with depth and pressure. The density at the surface is ρ0 Show that the density varies with pressure according to ρ=ρoekp (Where p is gauge pressure at any depth, and k is the compressibillity.) Find p as a function of depth, y.

A swimming pool of depth 2.5 m is filled with ordinary (pure) water (ρ = 1000 kg/m3). (a) What is the pressure at the bottom of the pool? 1.2550×105 Pa (b) When the pool is filled with salt water, the pressure at the bottom changes by 5.2 x103Pa. What is the magnitude of the difference between the density of the salt water and the density of pure water? Please show your work :)

50% of the volume of a boat, sailing down the Mississippi (where the water density ρ = 1000 kg/m3), lies above the surface of the river. The boat then enters the Gulf of Mex- ico, in which 51% of its volume lies above the surface. What is the density of the seawater in the Gulf of Mexico? Please write down the formulas and details on how you found everything!
