- Compressed natural gas, which can be modelled as methane, (CHa, Molecular weight-16, C,=2254 J/kgK; C=1738 J/kgK) is filled into a rigid 100 litre tank of a vehicle. The initial state of gas in the tank is 1 bar, 27°C, and the final pressure is 150 bar. The filling is done from a large reservoir at 300 bar, 27°C. Heat ioss during filling can be neglected, and the gas can be treated as ideal. Compute the final mass and temperature of the gas in the tank.arrow_forwardI've already found T2 and A2 for part A. They are T2 = 310.2K and A2 = .0139m^2. But I can't figure out how to find the rate of entropy production with units KW/K (that's what my questions seems to be asking for, but it may be a typo). All of the solutions for this problem here on Bartelby find the rate of entropy production with units KW / (K*kg).arrow_forwardSolve please, should 100% sure of ans. Air enters a well-insulated turbine operating at steady state with a negligible velocity at 4 MPa and 300 oC, It exits the turbine at 100 kPa pressure at 100 oC. The diameter of the exit pipe is 60 cm. The velocity at exit is 90 m/s. a. What is the volumetric flow are at the exit? Express your result in units of m3/s. b. What is the molar flow rate at the exit? Assume that at the exit conditions, air may be considered to behave like an ideal gas. Express your results in units of mols/s c. What is the mas flow rate? Express your result in units of kg/s.arrow_forward

- ) Two boilers, one with superheater(B1) and other without superheater(B2) are delivering equal quantities of steam into a common main. The pressure in the boiler and main is 20 bars. The temperature of the steam from a boiler with a superheater is 350oC and temperature of the steam in the main is 250oC. The steam in B2 is wet steam at 20oC. i) Draw a sketch of the problem with all thermodynamic properties from steam table shown on the sketch. ii) Determine the quantity of steam supplied by the other boiler.
