16 the oxygen sag caused by a cannery reaches a minimum do equal to 3.0 mg/l. upstream from the cannery, the river do is saturated at 10.0 mg/l, and it has no bod of its own. just downstream from the discharge point, the do is still essentially saturated (i. e., consider the initial oxygen deficit to be zero so the downstream deficit is propositional to the initial bod). by what percentage should the bod of the cannery waste be reduced to assume a healthy stream with at least 5.0 mg/l do everywhere?

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.

What is the main objective of using reheat rankine cycle?

A12 mm diameter shaft runs in a plain cylindrical bush 30 mm long that is located in an 18 mm diameter hole in a housing. the shaft-inner bush fit is h8 f and the outer bush-housing fit is h7-p6. make a fully cimensioned sketch of the bush with tolerances. find the maximum and minimum clearance or interference for both fits on the inner and outer diameters of the bush
