An extravascular pressure measurement system contains a catheter that is 1 m long and is 0.5 mm in diameter. It is filled with a saline solution at 20oC, which has a viscosity of 0.001 Pa*s. The isothermal compression of air (ΔV/ΔP) is 1 mL/cm. Assume that the volume modulus of elasticity of the sensor diaphragm is 0.49 x 1015 N/m5. Calculate the resonant frequency in Hz. Would you expect the catheter frequency response to be over-, under-, or critically-damped?– explain your reasoning.

Water in a partially filled large tank is to be supplied to the roof top, which is 8 m above the water level in the tank, through a 2.2-cm-internal-diameter pipe by maintaining a constant air pressure of 300 kpa (gage) in the tank. if the head loss in the piping is 2 m of water, determine the discharge rate of the supply of water to the roof top in liters per second.
