Question 14 a solution of methyl acetate c3h6o2 and water that is 25.% methyl acetate by mass is boiling at 94.7°c. the vapor is collected and cooled until it condenses to form a new solution. calculate the percent by mass of methyl acetate in the new solution. here's some data you may need: normal boiling point density vapor pressure at 94.7°c methyl acetate 57.°c 0.93gml 2360.torr water 100.°c 1.00gml 630.torr be sure your answer has 2 significant digits. note for advanced students: you may assume the solution and vapor above it are ideal.

Fluids at rest possess no flow energy. a)- true b)- false

Water at 70°f and streams enter the mixing chamber at the same mass flow rate, determine the temperature and the quality of the exiting stream. 0 psia is heated in a chamber by mixing it with saturated water vapor at 20 psia. if both streams enters the mixing chamber at the same mass flow rate, determine the temperature and the quality of the existing system.

Asingle-geared blanking press has a stroke of 200 mm and a rated capacity of 320 kn. a cam driven ram is assumed to be capable of delivering the full press load at constant force during the last 15 percent of a constant-velocity stroke. the camshaft has an average speed of 90 rev/min and is geared to the flywheel shaft at a 6: 1 ratio. the total work done is to include an allowance of 16 percent for friction a) estimate the maximum energy fluctuation b) find the rim weight for an effective diameter of 1.2 m and a coefficient of speed fluctuation of 0.10
