24. A container is filled with 800 g of water at 20 C. A 200 g piece of brass with initial temperature of 180 C is dropped into the water in order to cool it. Calculate the final (equilibrium) temperature of the water/brass system.
2. A hydraulic jack is operated by pushing down on a small piston with area of 2 in2. This action raises another cylinder with area of 400 in2. If you push down on the small cylinder with a force of 80 pounds, how much weight will be lifted by the larger piston?
3. In the previous problem, if you were to push the small piston down by a distance of 18 in, how much would this raise the larger piston? Assume that the fluid is incompressible.

Consider the hydraulic jack represented beside. It is filled
with mineral oil (a lubricating liquid). Assume that a person is
able to push the left piston (F1) with a maximum force of 343 N.
The diameter of the piston on the left is only 2 cm and that of the
piston on the right much larger at 40 cm.

An ice cube of mass 500 g at 0 °C is dropped into an insulated container of 1.0 kg of water that initially is at room temperature (25 °C), and eventually the system reaches equilibrium. The insulator is not perfect, so 20 kJ of heat flows from the room into the water during the process. 3. a. Calculate the entropy increase in the ice that melts into water. b. Calculate the entropy loss of the water that cools down. c....

10. Write a one-page summary of the attached paper? INTRODUCTION Many problems can develop in activated sludge operation that adversely affect effluent quality with origins in the engineering, hydraulic and microbiological components of the process. The real "heart" of the activated sludge system is the development and maintenance of a mixed microbial culture (activated sludge) that treats wastewater and which can be managed. One definition of a wastewater treatment plant operator is a "bug farmer", one who controls the aeration...
