1 kg of atmospheric air initially at 30 ºc and 60% relative humidity is cooled slowly, at a constant pressure of 100 kPa, to a final temperature of 5 ºc. a. What is the saturation pressure of water at the initial temperature? b. What is the partial pressure of water vapor (vapor pressure) at the initial condition? c. What is the partial pressure of dry air at the initial condition? d. What is the initial humidity ratio? e. What is...

please provide me with the solutions as fast as possible A gas mixture with id entical mass fractions for each component will have the identical mole fractions 1. T F as well. T F 2. The sum of the mass fractions for a real-gas mixture is equal to 1 The molar mass of Methane is 0.5182 kg/kmol. 3. A real-gas mixture has a compressibility factor of 0.49. Using the ideal gas relationship, 4. the volume of the mixture b. Underestimates...
SKMM 2423 QUESTION 4 a) Cold water flows through a metal pipe, which is not insulated The pipe is loc ated in am ambient air, which is at a higher temperature and humidity, What do you think would be observed on the surface of the pipe? Describe briefly the reason for this 5 marks) b) A sling psychrometer shows a dry bulb and wet bulb temperature readings of 25°C and 20°C, respectively. The atmospheric pressure is 101 325 kPa. Using...
a. Calculate the dry air and water vapor mass flow rates (lb/min) if the volume flow rate is 1,000 cfm, the humidity ratio is 0.025 lbv/lba, and the dry air density is 0.072 Iba/ft3. b. Assume the above air enters an evaporator coil at 90°F where it is cooled in a constant humidity ratio process until reaching the 100 % RH curve ( the temperature at that point is the dew point. The air then keeps dropping in temperature, following...
