Consider the flow of oil (density = 894 kg/m3 and viscosity = 2.33 kg/m. s) in a 40-cm diameter pipeline at an average velocity of 0.5 m/s. a 300-m-long section of the pipeline passes through icy waters of the lake. disregarding the entrance effects, determine the pumping power required to overcome the pressure losses and to maintain the flow of oil in the pipe

explanation:

earth's surface is mainly heated by the absorption of infrared radiation from the sun.

evaporation occurs because molecules in liquid water are warmed ( usually by the sun) and vibrate quicker, becoming less dense and rise.

condensation occurs because molecules in water vapor are cooled and therefore vibrate more slowly thus becoming more dense and eventually fall to earth.

lines of equal barometric pressure on a weather map are called: isobars : lines of equal temp on a weather map are called: isotherms.​

tbh i don't know the answer for this question
