What happens to the frequency response of a p23dd sensor , 6f, 1m, water filled catheter system (at 20 ˚ c) when a tiny pinhole leak occurs at the junction of the catheter and sensor? the leak allows a .40 ml/min flow for a pressure head of 100 mm hg (13.3kpa). plot frequency response curves for the system with and without the leak.

An important dimensionless parameter concerned with very high-speed flow is the mach number, defined as v/c, where v is the speed of the object such as an airplane or projectile, and c is the speed of sound in the fluid surrounding the object. for a projectile traveling at 1170 mph through air at 50 ˚f and standard atmospheric pressure, what is the value of the mach number?
