The output of a first order transducer is to be connected to a signal conditioner which also has first order dynamic characteristics. The transducer has known time constant of x milliseconds and static sensitivity of xx V/kPa while the signal conditioner has a time constant of y milliseconds and a static sensitivity of yy V/V. Determine the steady state response of this measurement system to an input signal of the form: P(t)=(A+B*sin(w*t) ) kPa.

An air-conditioning system consists of a heating section and an evaporative cooler. air enters the heating section at 10°c and 70 percent relative humidity at a rate of 30m^3/min, and it leaves the evaporative cooler at 20°c and 60 percent relatively humidity. if the air conditioning system operates at a total pressure of 98 kpa, determine (a) the temperature and relative humidity of the air when it leaves the heating section, (b) the rate of heat transfer in the heating section, and (c) the rate of water added to air in the evaporative cooler
