)what is the sensitivity k of the sensor in [v/n]? b) what is the sensor’s damping ratio, ? c) what is the natural frequency n of the sensor? d) it turns out that we can adjust the damping and thus alter the damping ratio in the sensor. we need the sensor to measure a dynamic signal with frequencies up to 90% of the natural frequency calculated in part (c). determine the range of damping ratios that would be acceptable to limit the magnitude response error to 10%.

Apump is used to circulate hot water in a home heating system. water enters the well-insulated pump operating at steady state at a rate of 0.42 gal/min. the inlet pressure and temperature are 14.7 lbf/in.2, and 180°f, respectively; at the exit the pressure is 60 lbf/in.2 the pump requires 1/15 hp of power input. water can be modeled as an incompressible substance with constant density of 60.58 lb/ft3 and constant specific heat of 1 btu/lb or. neglecting kinetic and potential energy effects, determine the temperature change, in °r, as the water flows through the pump.

Calculate the bore of a cylinder that has a stroke of 18 inches and an extension time of 6 seconds at a flow rate of 4 gal/min.
