Air is flowing in a 1.5 m2 wind tunnel at 200 m/s at a pressure of 250kPa, and temperature of 20°C at the entrance. Calculate:
(i) Mach number
(ii) Total Temperature
(iii) Total Pressure
(iv) Mass flow rate of air.

Expert Solution
i) Mach number- It is the ratio of local flow velocity to speed of sound in given number.
theredore, M(mach number)=v/c
M=200/340 ; c= velocity of sound (at 20 degrees)= 340m/s
M=0.588
#answers of question ii), iii) and iv) are given in following images:

A wing-body model is tested in a wind tunnel with a
flow of 100 m/s at standard sea-level conditions.
The wing area is 1.5 m^2 and the mean aerodynamic
chord length is 0.45 m. Measurements of lift force, L, and moment
about the center of gravity, MCG are made using the wind tunnel
force balance.
The lead mass is removed and a horizontal tail without
an elevator is added to the model. The distance from the airplane
center of gravity...

Fluid (air) enters a nozzle at 150 m/s, 26.85 oC, and at a
pressure of 200 kPa. Assuming isentropic flow, evaluate the
temperature and pressure of the fluid at a location where the speed
of fluid equals the speed of sound. What is the ratio of the area
at this location to the entrance area?

Water flowing along a horizontal pipe has a speed of 2.31 m/s
and a pressure of 4.25 atm. Further along, the pipe narrows so that
the cross-sectional area decreases by a factor of 6.17. What is the
pressure in the narrow section?

Assume that we wish to design a Mach 10 hypersonic wind tunnel
using air as the test medium. We want the static pressure and
temperature in the test stream to be that for a standard altitude
of 55 km. Calculate (a) the exit-to-throat area ratio, (b) the
required reservoir pressure (in atm), (c) the required reservoir
temperature, and (d) the exit velocity. What do these results tell
you about the special (and sometimes severe) operating requirements
for a hypersonic wind...

A water tunnel is mined through a mudstone rock mass at a depth
of 200 m. The rock mass consists of three fracture sets. One set is
the bedding planes; these are highly weathered, slightly rough
surfaces and are continuous with an orientation of 180/10. The
first number is the dip direction which is an azimuth measure from
the North. Dip direction is measured 90° clockwise from the strike.
The second number is the dip. The second set of fractures...
