The TSS concentration in the primary treated effluent is 150 mg/L, and TSS removal is 63 percent. The sludge has an average solids concentration of 6 percent and specific gravity of 1.045. What is the capacity of the sludge pump in m3/min per basin if the pump is used on a 15-min pumping cycle per h

A2-m rigid tank initially contains saturated water vapor at 100 kpa. the tank is connected to a supply line through a valve. steam is flowing in the supply line at 600 kpa and 300 c. the valve is opened, and steam is allowed to enter the tank until the pressure in the tank reaches the line pressure, at which point the valve is closed. a thermometer placed in the tank indicates that the temperature at the final state is 200°c. determine (a) the mass of steam that has entered the tank (b) the amount of heat transfer.
