The barometer shows a value of 700 mm Hg, the temperature of the dry ball is 55 °, the temperature of the wet ball is 30°C. Determine a. Relative humidity (RH) = answer % b. Absolute humidity = answer (kg water/kg air) c. Dew point temperature = answer (°C)

4. A gas is initially at an absolute pressure of 400 kPa. What is its final absolute pressure if its volume is doubled? Presume that the atmospheric pressure is 101.3 kPa. a. b. C. d. 800 kPa 200 kPa 100 kPa None of the above epica on ni

A child takes a helium balloon on a plane from Denver (with an air pressure of 0.83 atm) on a cool day when the temperature is 20.0oC to Boston (at sea level, with an air pressure of 1.0 atm) where the temperature is 5.0oC.  Assume that no gas escapes from the balloon during the flight.  What is the volume of the balloon in Boston, relative to its size in Denver? Group of answer choices The volume in Boston is 0.79 times the volume in Denver. The volume in Boston is 0.20 times the volume in Denver. The volume in Boston is 0.87 times the volume in Denver The volume in Boston is 1.3 times the volume in Denver. The volume in Boston is the same as the volume in Denver.

THERMODYNAMICS SUBJECT NEED ASAP Two spherical vessels of different sizes contain the same gas and are connected by means of a pipe with a valve. Sphere A has a diameter of 5 foot at the given pressure gauge of 50 kgf/cm². Sphere B contains the same gas at 20 kgf/cm² gauge. The valve is opened and when the properties have been determined, it is found out that the gauge pressure is 36 kgf/cm². The temperature at the two vessels before and after opening the valve is maintained at 21.1°C. If the barometric pressure is 750 torr and the gas inside the sphere is nitrogen, find the following:     The atmospheric pressure in psi  The diameter of Sphere B  The total mass of the gas after opening the valve  I hope you can all answer this question I know tutor can answer until 4 parts. Thank you will give thumbs up

A differential manometer is connected at the two points A and B as shown. At B air pressure is 9.84 N/cm2 (abs), find the absolute pressure at A using the following data. - Specific Gravity of oil as 0.89; - Distance, C = 22 cm; - Distance, D = 104 mm; Distance, E = 0.76 m.
