It is desired to flow water at 200C with an average speed of 0.04 m/s through a horizontal pipe with a diameter of 50 mm and a length of 1800 m. The pipe material is unknown and a visual inspection reveals corrosion on the inside walls of the pipe. 1. If possible, calculate the pressure drop in the pipe. If this is not possible, explain why.
2. Sketch the velocity profile you would expect in the pipe (speed vs radius)
3. Under the typical assumptions for pipe flow calculations, could any of the flow be considered irrotational? Explain

What precautions should you take to prevent injuries when dealing with heavy loads?

Apump is used to circulate hot water in a home heating system. water enters the well-insulated pump operating at steady state at a rate of 0.42 gal/min. the inlet pressure and temperature are 14.7 lbf/in.2, and 180°f, respectively; at the exit the pressure is 60 lbf/in.2 the pump requires 1/15 hp of power input. water can be modeled as an incompressible substance with constant density of 60.58 lb/ft3 and constant specific heat of 1 btu/lb or. neglecting kinetic and potential energy effects, determine the temperature change, in °r, as the water flows through the pump.

Water at 55c flows across a flat plate whose surface temperature is held constant at 95c. if the temperature gradient at the plate's surface for a given value of x is 18 c/mm, find a) local heat transfer coefficient. b) heat flux
