Figure 7 represents a belt driven system. Pulley B, which has a diameter of 2 points 16 inches, is being driven by pulley A, which has a diameter of 4 inches and
spinning at 60 RPMs. What is the ideal mechanical advantage of this
system?

An air conditioning system consist of a 5 cm diameter pipe, operating at a pressure of 200 kpa. the air initially enters the pipe at 15°c with a velocity of 20 m/s and relative humidity of 80%. if the heat supply throughout the process is 960 w, determine the relative humidity and the temperature at the outlet

Determine whether or not it is possible to compress air adiabatically from k to 140 kpa and 400 k. what is the entropy change during this process?

Burgers vector is generally parallel to the dislocation line. a)-true b)-false
