Answer:
11.541 mol/min
Explanation:
temperature = 35°C
Total pressure = 1.5 * 1.013 * 10^5 = 151.95 kPa
note : partial pressure of water in mixture = saturation pressure of water at T = 35°c )
from steam table it is = 5.6291 Kpa
calculate the mole fraction of H ( YH
)
= 5.6291 / 151.95
= 0.03704
calculate the mole fraction of air ( Yair )
= 1 - mole fraction of water
= 1 - 0.03704 = 0.9629
Now to determine the molar flow rate of water vapor in the stream
lets assume N = Total molar flow rate
NH = molar flow rate of water
Nair = molar flow rate of air = 300 moles /min
note : Yair * n = Nair
therefore n = 300 / 0.9629 = 311.541 moles /min
Molar flowrate of water
= n - Nair
= 311.541 - 300 = 11.541 mol/min
Answer:
vertical, and directed along an axis of symmetry of the cross-section
Explanation:
Shear is a force in an object is in the form of stress or strain. Shear strain is the ratio of length of deformation (extension) to the perpendicular length in the plane of the force applied. Shear stress, which is the stress that tends to shear a material, is the ratio of shear force applied on a surface to the area of the surface.
The shear formula can be used to determine the maximum shear in an object and is given by; τ = . It is applicable when the internal shear force is vertical and directed along an axis of symmetry of the cross-section.
