Liquid hazardous wastes are blended in a cstr to maintain a minimum energy content before burning them in a hazardous waste incinerator. the energy content of the waste currently being fed is 8.0 mj/kg (mega-joules/kilogram). a new waste is injected in the flow line into the cstr. it has an energy content of 10.0 mj/kg. if the flow rate into and out of the 0.20 m3cstr is 4.0 l/s, how long will it take the effluent from the cstr to reach an energy content of 9 mj/kg?

An air-standard stirling cycle operates with a maximum pressure of 600 psia and a minimum pressure of 10 psia. the maximum volume of the air is 10 times the minimum volume. the temperature during the heat rejection process is 100°f. calculate the specific heat added to and rejected by this cycle, as well as the net specific work produced by the cycle. use constant specific heats at room temperature. the properties of air at room temperature are r

The coulomb's law explains which of the following? select all the force between two charged objects is inversely proportional to the charge on each object. the force between two charged objects is directly proportional to the charge on each object. the force between two charged objects is directly proportional to the distance separating them. the force between two charged objects is inversely proportional to the square of the distance separat coulomb's law is similar to newton's 2nd law. if the force between two objects is f and the charge on both objects is doubled, the new force between the would now be 2f. if the force between two objects is 2f and the distance separating them is doubled, the new force between the objects would now o the be zf.
