An insulated piston cylinder device initially contains 0.01m^3 of steam at 473 K the force on the piston is such that it maintains a constant pressure of 400kpa Inside . A valve is now opened and steam at 1Mpa at 473 K is allowed to enter the cylinder until the volume inside increases to 0.04m^3 . Determine the final temperature of the steam and the amount of mass transfer
A tank is divided into two equal chambers by an internal diaphragm. One chamber containes methane at a pressure of 500 bar and a temperature of 20 C, and the other chamber is evacuated.
For an unknown alloy the stress at which plastic deformation begins is 400MPa and the modulus of elasticity is 120GPa. If the original specimen length is 76 mm, what is the max length to which it may be stretched without causing plastic deformatio..
a brass ring of 120-mm outside diameter is fits exactly inside a steel ring of 120-mm inside diameter when the temperature of both rings is 5 degrees C. knowing that the temperature of the rings is then raised to 55 degrees C
An underground limestone mine with production of 12,000 tons/day will use trucks for the main haulage between an ore pass and a hoist skip pocket. The hauling distance is 5500 ft. The main haulage drift is horizontal and is 12.5 ft wide and 12.5 f..
At the design flow, it is intended to have a relative depth of 0.8. At what minimum slope can it be laid such that the velocity is at least 2 ft/s at design flow and depositied solids will be scoured out by the deisgn flow
Calculate the moments M_A and M_B about point A for the forces applied at points A and B. Then, determine the resulting couple moment M_R. Assume that a positive moment produces a counterclockwise rotation whereas a negative moment produces a cloc..
A 3 kg mass is attached to one end of a 1 m long cord. The other end of the cord is attached to the center of a rotating disk (with radius greater than 1 m) that has a very large constant angular velocity.
two cohernt sources produce interference patern intensity ratio of bright fringe to dark fringe is 9/1. calculate the intensity ratio of sorces.
Water in the amount of 1 lb is contained in a rigid closed tank. Initially the water has a quality of 0.4 at a pressure of 10 lbf/in2. Through a stirrer, work is provided to the water in the tank until the pressure quadruples.
The ball is kicked so that it has a velocity of 0.5 m/s and the cord is pulled in at a rate of 0.2 m/s. Neglect friction so that the only important force on the ball is the tension in the cord. Find the tension in the cord when the radius is 0.25 ..
What is the reaction that occurs with hexanal and propanol (give both the hemiacetal and acetal products)?
