A pressure probe has a time constant of 12s when used to measure a particular gas flow. The gas pressure varies harmonically between 80psi and 260psi with a period of 15s (i. e., with a frequency of 0.067 Hz).
a. What is the pressure readout in terms of the input gas pressure?
b. What time constant should the probe have to give 99% of the correct pressure amplitude?

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.
