Look at the image on the left. Gear "B" has 36 teeth and gear "A" has 12. Calculate the gear ratio of this gear train if "B" is the driver. If "B" turns 4 complete revolutions clockwise how many times will "A" rotate and in what direction

During a steady flow process, the change of energy with respect to time is zero. a)- true b)- false

Assuming compressible flow of air and that the measurements are done at flagstaff a pitot static tube that gives the difference of total and static pressure measures 0.35 m of mercury. what is the velocity of air? assume the temperature to be 300k. (submit your excel or matlab calculation sheet)

For each of the following process: a) sketch the p-v diagram, b)sketch t-s diagram, c) sketch t-v diagram, d) sketch the boundary work on one of the diagrams (a, b or c) and e) sketch the reversible heat transfer on one of the diagrams (a, b or c): 1- isobaric process from compressed liquid to superheated vapor 2- isothermal process from compressed liquid to superheated vapor 3- isentropic process from compressed liquid to superheated vapor
