In the two-pipe system, water flows continuously from the inner pipe and air from the outer pipe (steady-state). ˙The pressure change in both pipes is negligible. In addition, heat interaction with the environment, kinetic and potential energy changes are also neglected. In this system shown in Figure 1, the water flowing from the inlet number 1 is in the state of saturated vapor (gas). In this case, calculate the outlet temperature (T2) for the given system, using the ideal gas approximation for air. (it should be solved iteratively.) (Please solve it on paper and solve it line by line. When you type it, it becomes too complicated to understand. Also please explain your solution and don't write too close. Thank you for your effort)

Q1- Suppose that we have two system to increase the air temperature from 17°C to 52°C and both of them operating at constant air pressure as shown in below figures. System 1: The air temperature is increased as a consequence of the stirring of a liquid surrounding the line carrying the air. T=17°C P=100 kPa Viscous Fluid T=17°C P=100 kPa System 1 System 2: The air temperature is increased by passing it through one side of a counter-flow heat exchanger. On the other side, steam condenses at a pressure of 100kPa from a saturated vapour to a saturated liquid. Saturated liquid water P=100 kPa 2 T=52°C P=100 kPa Saturated water vapour P=100 kPa System 2 2 T=52°C P=100 kPa Both systems operate under steady conditions and are sufficiently insulated to prevent significant heat transfer with the surroundings. For each of the two systems, calculate the rate of entropy production, in

Problem 1 a) In an open vessel, a certain volume V of water is perfectly agitated by means of an impeller 20 cm in diameter D. Consider a case in which the impeller steadily rotates at 150 RPM (=revolutions per minute) Draw up a proper energy balance to find how temperature changes with time as a result of the power input øw, also named P, by the revolving impeller. • This Pis given by the formula P = 3.5 PN°D° in which N denotes the impeller speed in revolutions per second. Calculate P. When V = 120 litre and the specific heat of water amounts to 4.2 kJ/kgK, calculate the temperature increase of the water after one hour of stirring.
Q2. solve all parts A reversed reversible heat engine extracts heat Q1-22 from a cold reservoir at temperature Tcold = 270K to supply heat to a rigid pressure vessel filled with a system of wet steam of mass m=10kg. The arrangement is depicted in Fig. Q2, where heat supplied by the reversed engine causes the pressure of the system to rise from p₁ = 2 bar at state point 1 to p₂ = 10 bar at state point 2. Subsequently, the reversed engine is reversed, and heat is extracted from the steam to produce work W2-1, which returns the system back to state point 1, i.e., the system undergoes a cycle. Information recorded at the state points depicted in the figure is as follows: State point 1: dryness fraction ✗₁ = 0.1 and pressure p₁ = 2 bar. State point 2: P₂ = 10 bar. 2-1 Assume that the only transfers of heat to take place are those labelled in Fig. Q2, i.e., 02, 0, and Additionally, assume that the role of the rigid pressure vessel is solely limited to containment, so that any changes to its…
