The receiving river in the spring months (with a temperature of about 10-15 °C) has no initial deficit in the outfall region of partially treated sewage with BODL of 18 mg/L and a decay coefficient of 0.21. Please locate the downstream river section where the maximum DO sag might occur. Will the water quality result in potential negative impacts on aquatic organisms in the river? Assuming that the re-aeration coefficient is 0.31 per day and the average water velocity is 0.4 m/s.

If the temperature inside a room is 25°C and the temperature outside is ?10°C: a. What is the maximum relative humidity that can be accommodated inside the room before the window fogs over? (Assume the inside of the window is not insulated from the outside temperature). b. If it is a double-pane window such that the inside of the window is perfectly insulated from the outside, what will the maximum relative humidity be?

Starting with a spring index of C = 10, design a compression coil spring of 302 stainless wire with squared ends. The spring is to deflect y = 50 mm, for an applied force of F = 90 N and to close solid when ys = 60 mm. At closure, use a design factor of 1.2 guarding against yielding. Select the smallest diameter wire where wire diameters are available in 0.2-mm increments between 0.2 to 3.2 mm. For the design,...
