In a geothermal power plant, the used geothermal water at 80°c enters a 15-cm-diameterhexagon and 400-m-long uninsulated pipe at a rate of 10 kg/s and leaves at 70°c beforebeing rejected back to the ground. windy air at 15°c flow over the pipe. disregardingradiation, determine the average wind speed that cools the water.

1 the 4 is sig

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
