The percentage humidity of air at 25°C and a total pressure of 790 mmHg is 60%. Calculate the relative humidity and the partial pressure of the water vapor in the air If the percent humidity of air (30 °C, total pressure 150 kPa) is 44 % and the saturation pressure of water vapor at that temperature is 6 kPa, the percent relative humidity and the absolute humidity of air are

explain why the basement of a house often has high relative humidity in the summer? A   Hot air containing moisture is brought inside where it cools increasing the SMR while the MR stays constant B   Hot air containing moisture is brought inside where it cools decreasing the MR and while the SMR remains constant C   Hot air containing moisture is brought inside where it cools increasing the MR and while the SMR remains constant D   Hot air containing moisture is brought inside where it cools decreasing the SMR while the MR stays constant

Calculate (a) the specific volume, (b) Enthalpy, and (c) absolute humidity at 40 udaraC and relative humidity at 49%, at a barometric pressure of 740 mm Hg. (a) Specific volume =    m3 / Kg.(b) Enthalpy =     (kJ / kg air)(c) Absolute humidity =    (kg water / kg air)

I need the answer as soon as possible
