A100 -l tank is filled with pure water when an inflow pipe is opened and a sugar solution with a concentration of 20 g/l flows into the tank at a rate of 0.1 l/min. the solution is thoroughly mixed and flows out of the tank at a rate of 0.1 l/min. (a) find the mass of sugar in the tank at all times after the inflow pipe is opened. (b) what is the steady-state mass of sugar in the tank? (c) at what time does the mass of sugar reach 95 % of its steady-state level?

On a average work day more than work place firs are reorted

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.

Coiled springs ought to be very strong and stiff. si3n4 is a strong, stiff material. would you select this material for a spring? explain.
