- Argon gas flows through a well-insulated nozzle at steady state. The temperature and velocity at the inlet are 570°R and 150 ft/s, respectively. At the exit, the temperature is 460°R and the pressure is 40 lb/in². The area of the exit is 0.0085 ft². Use the ideal gas model with k = 1.67, and neglect potential energy effects. Determine the velocity at the exit, in ft/s, and the mass flow rate, in lb/s.An increase in pressure of a liquid from 7.5 MPa to 15 MPa results into 0.2 percent decrease in its volume.

- Consider the thermal system shown below. The temperature of the inflow liquid is kept constant, and the liquid inflow rate G kg/s is also kept constant. For t <0 the system is at steady state, wherein the heat input from the heater is U kcal/s and the temperature of the liquid in tank 2 is 0,°C. At t 0 the heat input is changed from U to U + u where u is small. This change will cause the temperature of the liquid in tank 2 to change from 02 to 02 +82. Taking the change in the heat input from the heater to be the input to the system and the change in the temperature of the liquid in tank 2 to be the output, obtain the transfer function 02(s)/U(s). Assume that the thermal capacitances of tanks 1 and 2 are Ci kcal/°C and C2 kcal/C, respectively, and that the specific heat of the liquid is c kcal/kg°C. The steady-state heat flow rates from tanks 1 and 2 are the same, Q kcal/s. The changes in and heat flow rates from tanks 1 and 2 are q2, respectively. U +u G Tank 1 O+ 0, O+ 0, O+ 42 Tank 23.
