Unformatted text preview: long. If each house uses a maximum of 50 gal/hr (at peak demand) and the pressure in the distribution system is not to be less than 30 psig at any point, how many homes can be served by the water main? Ignore losses due to fittings and expansion/contractions. FYI: Most subdivisions have between 140160 houses. 3. You are selecting a pump that will be used to move sludge in a waste stream. In the lab, you measure the viscosity of the sludge and conclude that it can be described as a power law fluid with a flow index of 0.45, a viscosity of 7 poise at a shear rate of 1/sec, and a density of 1.2 g/cc. This is to travel through a 3 inch Sch. 40 pipeline 1000 feet long at a flow rate of 100 GPM. What is the required horsepower of the pump?...
