The ideal gas law relates the pressure P, volume V, absolute temperature T (Kelvin), and amount of gas n. The law is P = mAT where R is the gas constant. An engineer must design a large natural gas storage tank to be expandable to maintain the pressure constant at 2.2 atmospheres. In December when the temperature is -15°C, the volume of gas in the tank is 28,500 ft°. What will the volume of the same quantity of gas be in July when the temperature is 31°C? (Hint: Use the fact that n, R, and P are constant in this problem. Note also that Kelvin = °C+273.2)

You, a process design engineer, are tasked to build a powerplant with a net output of 1 MW. First, in an industrial boiler, coal is burned to heat and pressurize 1.6 kg/s of water pumped from an underground reservoir (25 oC, 1 atm) to High Pressure Steam (44 atm, 450 oC). The industrial boiler is insulated, but due to the high temperatures and the nature of the process there are inevitably heat losses. As such, the total heat losses of the whole system is around 20% of the heat from the coal. The High-Pressure Steam, moving at a linear velocity of 70 m/s, is then used to drive a turbine. The low pressure steam from the turbine is used to preheat the boiling water and then released to the atmosphere as saturated steam (100oC and1atm) at a velocity of 10 m/s via an exhaust 10 m above the turbine inlet. How much heat is needed for the powerplant? Use the following values of enthalpy: Water from reservoir 25oC; 1atm H=104.93 kJ/kg High Pressure Steam 450oC; 44atm H=3324.63 kJ/kg Low…

Water is being pumped the through one inch diameter piping arrangement to a higher elevation (5 meters up). Assume incompressible fluid conditions and some heat losses to the surroundings. At the inlet water pressure is 1 bar, temperature 15C, and volumetric flow rate is 0.02 m3/s. At the exit pressure is 2.2 bar, temperature is 10C and velocity of the stream is 40 m/s. Determine: a.Density of the inlet stream using NIST tables. b.Mass flow rate [kg/s] c.Determine h2 from known p2 and T2 using NIST tables d.Find heat rate removed from Q=m(h1-h2) Use Energy Balance Equation with enthalpy difference and in the units of kW to find pumping power in kW. NOTE: The heat is removed from the system, so it should be negative in your equation! show all steps please thanks
