Saturated humid air at 200 kpa and 15c is heated to 30c as it flows through a 4-cm diameter pipe with a velocity of 20 m/s. disregarding the pressure losses, calculate the relative humidity at the pipe outlet and the rate of heat transfer, in kw, to the air.

beta is electron from nucleus

something from nucleus has changed, but charge must be same for cons of charge

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force
