Q3/ A rigid, insulated tank that is initially evacuated is connected through a valve to a supply line that carries steam at 1 MPa and 300°C. Now the valve is opened, and steam is allowed to flow slowly into the tank until the pressure reaches 1 MPa, at which point the valve is closed. Determine the final temperature of the steam in the tank. Assumptions 1 This process can be analyzed as a uniform-flow process since the properties of the steam entering the control volume remain constant during the entire process. 2 The kinetic and potential energies of the streams are negligible, KE=PE= 0. 3 The tank is stationary and thus its kinetic and potential energy changes are zero; that is, AKE = APE = 0 and AEsystem =AUsystem. 4 There are no boundary, electrical, or shaft work interactions involved (W=0). 5 The tank is well insulated and thus there is no heat transfer (Q=0).

3) In a fixed volume container with a volume of 0.1 m^3, initially there is saturated water vapor at 130°C. The vessel is connected to a pipe through which steam flows through a valve at 2 MPa pressure and 350°C temperature. Then the valve opens and steam enters the container. Meanwhile, the temperature of the steam in the container remains constant at 130°C due to the heat transfer to the environment. When it is observed that 3/4 of the water in the container covers the liquid phase by mass, the valve is closed. Calculate a) the final pressure in the container, b) the mass of steam entering the container, c) the heat transfer to the environment.
Question 3 Consider the turbocharger of an internal combustion engine. The exhaust gases enter the turbine at 450°C at a rate of 0.02 kg/s and leave at 400°C. Air enters the compressor at70°C and 95 kPa at a rate of 0.018 kg/s and leaves at 135 kPa. The mechanical efficiency between the turbine and the compressor is 95 percent (5 percent of turbine work is lost duringits transmission to the compressor). Using air properties for the exhaust gases, determine:(a).The turbine power output, compressor power input, air temperature at the compressor exit,(b).The air temperature at the compressor for the case of isentropic process and isentropic efficiency of the compressor.
CO2 is needed in a surgical suite for abdominal laparoscopic surgery. You have already designed a nozzle to step down the pressure from the gas cylinder to the delivery hose. The well-insulated delivery hose has a 2.2 mm inner diameter. The inlet conditions to the delivery hose are 103 psia and 17°C. Typically, the surgeon uses 4 to 6 L/min of gas at pressures between 10 to 20 mm Hg to inflate the peritoneal cavity; however, the delivery system must be able to provide flow rate of 17.5 L/min at 20.0 mm Hg for safety. The surgeon will use a pin valve to control the flow rate and maintain the operating space. The gas temperature should not be any colder than 10°C when delivered to patient, or tissue damage might occur. Determine the acceptable delivery hose length to meet the surgical criteria. State assumptions.
An assembly of piston cylinder system shown in Figure Q1 had 1 MPa pressure and 400°Ctemperature. The system is cooled to 250°C at a constant pressure and mass of the steam is 0.8 kg. (a) Determine the compression work. (b) If the stopper position is at 40% of the initial volume determine the temperature when thepiston immediately touches the stopper and discuss on the nature of the vapor.
A piston cylinder contains 1.25 kg water at 25°C with a constant load on the piston such that the pressure is 300 kPa. A nozzle in a line to the cylinder is opened to enable flow to the outside atmosphere at 100 kPa and 25°C. The process continues until 85% of the initial mass has flowed out. At this point, the temperature of water increased by 10°C. Assume that the process is done in an Water isobaric manner. Write the mass and energy balance equations and calculate the work (kJ) and heat (kJ) involved in the process if the exit velocity is 40 m/s. For compressed liquid, assume the substance is a saturated liquid at the given temperature.
The case of a piston-cylinder device provided with stops is presented. Initially, the water supports the weight of the piston, and the force of the atmosphere is 300 kPa and 0.4 m3/kg. The water is heated until it reaches a saturated steam condition and the plunger rests on the stops. With the piston on the stops, the water is heated to a pressure of 700 kPa. Plot the curves of the processes on the p-V and T-V diagrams indicating the initial and final states of the guide. On both the p-V and T-V diagrams plot the isotherms passing through both states, and show their values in °C.

An expansion valve is a part of an adiabatic rigid steam boiler. Steam's initial pressure and temperature are set to 1 MPa and 350°C. In a matter of seconds, the tank's expansion valve was opened, causing it to fill to capacity. Calculate the pressure in the expansion valve if the steam flowing through it has a temperature of 300C.
Q2- Consider two ways to compress 2 kg/s of air (an ideal gas with R = 0.287 kJ/kg K and constant heat capacities: cv = 0.718 kJ/kg·K, and cp = 1.005 kJ/kg K) from an inlet Pin = 100 kPa and Tin = 20°C to an outlet Pout = 50 MPa and a heat loss of 150 kW. In this case the outlet temperature is Tout =700°C. Find the work in this case
4- Consider a water mixer operating at constant pressure, receiving water at the first inlet at I MPa and 30 °C and superheated vapor at the second inlet at I MPa and 300 °C. If the required exit temperature is 120 °C, determine the mass flow ratio of the two inlets.
determine the value of AB. Water is to be heated from 20°C to 70°C as it flows through a 40 mm internal diameter and 600 mm long tube. The outer surface of the tube is wrapped with electrical wire which acts as an electrical resistance heater. The heater provides uniform heat flux throughout the surface of the tube. The outer surface of the heater is well insulated. At steady state if the system provides hot water at 0.2475 kg/s, determine the power rating of the resistance heater and the inner surface temperature of the pipe at the exit.
