A light airplane attains an airspeed (speed of the plane with
respect to the air) of 500km/hr. The pilot sets out for a
destination 800km due north, but discovers that the plane must be
pointed 20.0◦ east of due north for the plane to reach there
directly (i.e., the nose/front of the plane is pointed 20.0◦ east
of due north, but the plane itself moves due north as seen by
someone on the ground). The plane arrives in 2.00hr. P,...

A room has a volume of 225 m3. An air-conditioning system is to replace the air in this room every 56.6 minutes, using ducts that have a square cross-section. Assuming that air can be treated as an incompressible fluid, find the length of a side of the square if the airspeed within the ducts is (a) 2.00 m/s and (b) 5.00 m/s.

Question 1: Derive an expression for the shear stress at the pipe wall when an incompressible fluid flows through a pipe under pressure. Use dimensional analysis with the following significant parameters: pipe diameter D, flow velocity V, fluid viscosity u and density, p of the fluid.

The fluid in the cylinder is incompressible. When the cross
section of thick and thin cylinder are known, and also the
difference of the pressure p2-p1(thick(p2) and thin(p1)) can be
estimated, then find the volume flow rate of this fluid.
