Problem 13.056 - DEPENDENT MULTI-PART PROBLEM - ASSIGN ALL PARTS NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. An insulated tank that contains 1.0 kg of O2 at 15°C and 300 kPa is connected to a 2-m³ uninsulated tank that contains N2 at 50°C and 500 kPa. The valve connecting the two tanks is opened, and the two gases form a homogeneous mixture at 25°C. Assume To = 25°C. 0₂ 15°C 300 kPa N₂ 2 m³ 50°C 500 kPa

303 nt inces Required Information NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. Steam flows steadily through an adiabatic turbine. The inlet conditions of the steam are 4 MPa, 500°C, and 80 m/s and the exit conditions are 30 kPa, 92 percent quality, and 50 m/s. The mass flow rate of the steam is 13 kg/s. The properties of the steam are v=0.086442 m³/kg, h = 3446 kJ/kg, and 2 = 2437.7 kJ/kg. P = 4 MPa 7-500C VVER Steam P₂ = 30 kPa 4y=0.92 V₂50 m/s Determine the turbine inlet area. The turbine inlet area is m².

As shown in the figure, a 320-ft³ tank contains 25 lb of H₂O initially at 30 lbf/in². The tank is connected to a large steam line carrying steam at 200 lbf/in², 450°F. Steam flows into the tank through a valve until the tank pressure reaches p2 = 100 lbf/in² and the temperature is 400°F, at which time the valve is closed. Step 1 Steam at 200 lbf/in.2, 450°F Am 12 = i (1) Valve AD Determine the amount of mass that enters the tank, in lb. lb (1) Determine the amount of mass that enters the tank, in lb, and the heat transfer to the tank from its surroundings, in Btu. Tank Initially: 30 lbf/in.², m₁ = 25 lb (2) Finally: P₂ lbf/in.², 400°F.

D Question 1 Use this figure for Questions 1 to 5. A hot-water stream at 90 °℃ enters an insulated mixing chamber with a mass flow rate of mh=0.75 kg/s where it is mixed with a stream of cold water at 25°℃ in a steady state steady flow process. It is desired that the mixture leaves the chamber at 45°℃ as shown in the Figure Hot water P₁=300 kPa T₁=90°C m=0.75 kg/s Cold water P-300 kPa T: 25% m=? 1 2 Mixing Chamber Mixed warm water Ps-300 kPa T=45°C m3 For Question 1: The specific enthalpy of the hot water, h1, in kJ/kg is
