Mount Rainier is the highest mountain in the U.S. state of Washington; it rises 4392 m above sealevel (which is approximately half the height of Mount Everest). If the ambient temperature is 15 °C at sealevel, determine the absolute pressure at the top of Mount Rainier. HINT: The universal gas constant in standard SI units is 8314.3 J/kmol-K Altitude (m) 8964 4392 2025 Sea level Mount Everest Mount Rainier (Washington) Clingman's Dome (Smoky Mountains National Park)

QUESTION 2 Under constant pressure P = 1 atm an ideal gas of 1.5 mol undergoes cooling from 120°C to 30.0°C, and = 3/2R. Please calculate q, w, AU, and AH (all units are J). Cv.m Please enter all four answers using scientific notation (E notation) with three significant figures, such as 2.30E4 (=23000). If the answer is negative, please do not forget the negative sign. If answer is zero, please just enter 0 without decimal. (1) q= (2) w= (3) AU= (4) ΔΗ=

Superheated steam at 300°C and 1 bar (absolute) is to be fed to a heat exchanger. It is produced by mixing an available stream of saturated steam at 1 bar discharged from a turbine at a rate of 1150 kg/h with a second stream of superheated steam at 400°C and 1 bar. The mixing may be considered adiabatic. Calculate the amount of superheated steam at 300°C produced and the required volumetric flow rate of the 400°C steam. a. b. C. d. e. Draw a picture of your system. Label input and exit streams and include mass flow rate, temperature, and pressure. Use variables to define any unknowns. Determine enthalpies for all streams at appropriate conditions. See attached steam table. All enthalpy values in the steam table are in kJ/kg. Write the open system energy balance and eliminate unnecessary terms (include brief justifications). Determine the mass flow rate of saturated steam. Please give your answer in kg/hr. Determine the volumetric flow rate of the saturated steam. Please give your…
