A streamline in a steady flow of a constant density ρ=1.94 slug /ft cubed
fluid is horizontal. The fluid may be assumed to be idea, meaning it has
no viscosity. At a point on the streamline the velocity is 2.5 ft/sec and a
pressure of 8psi. At some distance downstream, a stagnation point occurs
on this stream line at the tip of a pitot tube. What is the pressure at this
stagnation point?
Point 2 is a stagnation point, V2=0. Horizontal pipe z1=z2
A Manometer containing mercury (Hg S=13.6) and air is attached to a
tank that contains water and air. All of these fluids are static. Compute the
water pressure at the location of the pressure gage in the tank.
A water tank has a circular base of diameter 15 meters. A circular pipe
(pipe A) flowing into the tank and has a diameter 20 cm. The elevation of
the water surface in the tank is observed to be dropping (going down) at a
rate of 3 cm/min compute the flow rate Q in pipe B.
A standardsized 55gallon steel drum (a cylindrical container) containing
