Air temperature at 20°c can hold 14 grams of water vapor. if an air mass is 20°c and has seven grams of water vapor, what would its relative humidity be?

relative humidity fro 14 gm water vapor is 100%

relative humidity fro 7 gm water vapor is 50%

Explanation:

Given data:

Air temperature of 20 degree celcius can sustain 14 gram water vapor

from table -  saturation mixing ration

saturation mixing ration for air temperature at 20 degree celcius is 14g/kg

therefore relative humidity is %

Air temperature of 20 degree celcius can sustain 7 gram water vapor

from table -  saturation mixing ration

saturation mixing ration for air temperature at 20 degree celcius is 14g/kg

therefore relative humidity is %

initial speed when it is dropped is 150 ft/s

now at the same moment the acceleration due to gravity is perpendicular to its velocity

so as we know that

now we have centripetal acceleration a = 32 ft/s^2 as its perpendicular to velocity

while tangential acceleration at the same moment will be zero

so

now radius of curvature is given as

so the radius of curvature just after it is dropped is 703.125 ft
