2.5. Fig P-2.5 shows a thermometer plugged into a bath of temperature . Obtain the transd function (s)/(s) of the thermometer and its electrical analogue. (The thermometer may la considered to have a thermal capacitance C'which stores heat and a thermal resistance which limits the heat flow). How the temperature indication of the thermometer will vary with t after the thermometer is suddenly plugged in? Concentrated salt solution Bath Water @ Fig. P-2.5. 2.6. The scheme of Fig P-2.6 produces a steady stream flow of dilute salt solution with controlled concentration Co. A concentrated solution of salt with concentration C, is continuously mixed with pure water in a mixing valve. The valve characteristic is such that the total flow rate Q through it is maintained constant but the inflow Q, of concentrated salt solution may be linearly varied by controlling valve stem position x. The outflow rate from the salt mixing tank is the same as the flow rate into it from the mixing valve, such that the level of the dilute salt solution in the tank is maintained constant. Obtain the transfer function C(s)/X(s) If from fully closed position, the valve stem is suddenly opened by x, determine the outstream salt concentration Co as a function of time.
