Air flows into the atmosphere from a nozzle and strikes a
vertical plate as shown in below figure. The reading on the
pressure gage was 1.82 kPa. Determine the horizontal force required
to hold the plate in place. Assume the flow to be incompressible
and frictionless. Also consider the density of air is 1.23 kg/m3
and neglect the air weight.

Air flow over a cylinder of radius R- 150mm is modelled as a steady, frictionless and incompressible flow. The vector form of the velocity field is 1" The freestream velocity far away from the cylinder is 75m/s and the static pressure is 101.3kPa. Note that this is similar to worked example 5.1 done during the lecture. However, now you know the Bernoulli equation can be used along a streamline...so: Find a) The stagnation pressure at the leading edge of the...

Consider incompressible, steady, inviscid flow at vertical velocity vo though a porous surface into a narrow gap of height h, as shown. Assume that the flow is 2D planar, so neglect any variations or velocity components in the z direction. Find the x-component of velocity, assuming uniform flow at every x location. Find the y-component of velocity. Find an expression for the pressure variation, assuming that the pressure at the outer edge of the gap is Parm (hint: we can...
