Problem 5. A 1000 cubic foot room is initially at standard temperature and pressure. A resistance heater in the room is consuming 1500W of electricity. What is the air temperature of the room after 3 hours? Assume the room acts as an isolated system. Hint: The specific heat of a substance is the amount of heat it takes to warm one unit mass of material by one degree. The specific heat of air (assuming constant volume) can be taken as C₂ = 700J/kg°C. This relates the total heat added to the system to its temperature rise.
! Required information NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. A piston-cylinder device initially contains 1 kg saturated liquid water at 200°C. Now heat is transferred to the water until the volume quadruples and the cylinder contains saturated vapor only. The saturated liquid properties of water at 200°C 3 are vf= 0.001157 m³/kg and uf- 850.46 kJ/kg (Table A-4). Water mkg 200°C Q Determine the final temperature and pressure. (You must provide an answer before moving to the next part) The final temperature is The final pressure is °C. kPa.

b) A tank shown in Figure-2 below is used to mix methanol and salt. The tank initially contains 1 m³ of methanol. Salt is provided into the tank with a volumetric flow rate of Fsalt= 0.2 m³ s¹. A stream with perfectly mixed methanol and salt leaves the tank with a volumetric flow rate of F = 0.1 m³ s1. As the flow is unsteady, the volume of mixture in the tank, V(t), is a function of time. Fsalt=0.2 m³/s Psalt=2160 kg/m³ V(t) F=0.1 m³/s Figure-2: A mixing tank of methanol and salt. d(V (t)Psalt) dt Salt+methanol The mass balance of salt in the tank is given by, d(V (t) (Psalt +Pmethanol)) dt = Fsalt Psalt - FPsalt where Psalt is the density of salt and equal to 2160 kgm ³. The total mass in the tank is given by, = Fsalt Psalt - FPsalt - FPmethanol where Pmethanol is the density of methanol and equal to 800 kgm-³. When the tank contains V = 0.5m³ of mixture, what is the mass of salt in the tank? Use the explicit Euler finite difference method to discretise the balance equations. (Hint:…
b) Steam generators are a type of heat exchanges that are used in power plants to generate steam at desired pressure and temperature (Fig. Q1.b). In a steam generator, saturated liquid water at 30°C enters a 60-mm diameter tube at the volume flow rate of 12 L/s. After exchanging heat with hot gas, the water changes to steam and leaves the generator at a pressure of 9 MPa and a temperature of 400°C. During this process, the diameter of the water/steam tube does not change. Steam out Gas out Hot gas in Liquid water in Fig 2. Schematic of the steam generator in Q1.b. (i) Calculate the steam mass flow rate (ii) What is the inlet velocity of the steam? (iii) What is the exit velocity of the steam?
