Yes, there is friction and heat is produced. This heat is, however, not felt outside the pipe if water is colder than the pipe as it absorbs the heat. If the pipe is colder than the water, the pipe attains a temperature of equilibrium temp + rise in temp due to frictional heat.

Yes there is friction. There is also heat production. The friction is why The tops of Fire Hydrants are painted different colors. The colors tell the firemen how much water can safely be pumped every minute from that hydrant. To see the heat effect, take a piece of pipe and freeze it in a block of ice with the ends sticking out. Then when it is hard frozen, put the ice in a pool of water from a hose. hook the hose up to the pipe. The ice around the pipe will melt faster secondary to the friction.

Yes, there is definitely friction between the water and the iron pipe if there is flow of water. Motion always causes friction.
And that friction does generate some heat but that will be absorbed by water as water has a very high specific heat.

Yes there is friction in iron pipes with water flowing in them. This friction generates heat but not enough to make a significant difference. The biggest effect is the pressure loss across the pipe.

Yes, and it does and like all friction it is converted to heat. The amount of heat depends on the amount of friction. I've accidently allowed high pressure pumps to recirculate and the resulting explosion convinced me it was a bad idea.

fluid friction is termed as viscosity there is definitely a friction and may be a heat energy is developed but water can absorb the heat havin a good heat capacity.The heat generated won't evaporate the water.

Yes u r question is 100% correct. It does generate a neglegible amount of heat due to friction.

PRESSURE OF WATER INSIDE THE PIPE CANNOT CAUSE FRICTION AND HENCE HEAT.
IF WATER IS FLOWING THEN THERE IS RELATIVE MOTION BETWEEN PIPE WALL AND WATER CAUSING FRICTION. THERE IS ALSO FRICTION WITHIN THE LIQUID BETWEEN THE MOLECULAR LAYERS DUE TO RELATIVE LAYERS OF MOTION. THIS FRICTION GETS CONVERTED TO HEAT.

yes there might be friction,but the heat produced will depend on the quantity of water present & it's hardness

yes there must also be productin of heat depending upon they velocity of water
