Two long rectangular settling basin are operating in parallel to treat 5 million gallons per day (mgd) of coagulated water. a length-to-width (l: w) ratio of 4: 1 and length to depth (l: d) ratio of 10: 1 will be used in design. overflow rate 1000 spd/ft a. determine the dimensions of the settling basin in feet. b. calculate the detention time of each basin in hours. c. determine the length of the efluent weir in each basin if the weir loading rate is not to exceed 12, gpd/ft. note: in your problem, replace 5 by 7.5.

When using the ohmmeter function of a digital multimeter, the leads are placed in what position relative to the component being tested? a. parallel b. control c. series d. line

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.

Which from the following instrument is commonly used to detect the high pitch butzing sound in bearings? [clo4] a)-digital ultrasonic meter b)-infrared camera c)-spectroscopic d)-vibrometer
