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.

Aloaded platform of total mass 500 kg is supported by a dashpot and by a set of springs of effective stiffness 72 kn/m. it is observed that when the platform is depressed through a distance x = 12.5 cm below its equilibrium position and then released without any initial velocity; it reaches its equilibrium position in the shortest possible time without overshoot. find the position and velocity of the loaded platform 0.10 sec. after its release. if a further load of 400 kg is added to the platform, find, i) the frequency of damped vibrations, and i) the amplitude of vibration after 2 complete oscillations, given that the initial amplitude is 15 cm.

An air conditioning system consist of a 5 cm diameter pipe, operating at a pressure of 200 kpa. the air initially enters the pipe at 15°c with a velocity of 20 m/s and relative humidity of 80%. if the heat supply throughout the process is 960 w, determine the relative humidity and the temperature at the outlet
