Calculate the local reynolds number at a point 0.1 ft aft of the leading edge of a wing, which is being tested at sea level, standard day conditions, and at 800 ft/s (545 mph) true airspeed. what type of boundary layer exists at this point? assume recrit = 5 x 10^5

What difference(s) did you notice using a pneumatic circuit over hydraulic circuit.explain why the pneumatic piston stumbles when it hits an obstacle.

Abrake has a normal braking torque of 2.8 kip in and heat-dissipating cast-iron surfaces whose mass is 40 lbm. suppose a load is brought to rest in 8.0 s from an initial angular speed of 1600 rev/min using the normal braking torque; estimate the temperature rise of the heat dissipating surfaces.
