Consider two di˙erent streams of air, both with a relative humidity of 65%. Stream A has a temperature of 15◦C, and stream B has a temperature of 25◦C. The mass flow rate of dry air is the same in both streams. Which stream has a higher mass flow rate of water

stream B.

Explanation:

Stream B has higher mass flow rate of water due to higher temperature i.e. 25◦C as compared to stream A which has a lower temperature i. e. 15◦C because temperature affect the viscosity of liquid. Higher temperature make liquid or water thinner which means lower viscosity. This thinning of liquid make easier the flow of water in the pipes or other medium with the increase in temperature.

electric field is a function of 1/r^2

yes, the force per unit charge for a point charge is inverse square law.
