Acentrifugal pump delivers 2.1 m^3/min of water at 20°c when the brake horsepower is 22 and the efficiency is 71 percent. (a) estimate the head rise in m and the pres- sure rise in kpa. (b) also estimate the head rise and horse- power if instead the delivery is 2.1 m^3/min of gasoline at 20°c

The force on a cutting tool are 2600n vertically downward and 2100 horizontal. determine the resultant force acting on the tool and the angle at which it acts.

Calculate the bore of a cylinder that has a stroke of 18 inches and an extension time of 6 seconds at a flow rate of 4 gal/min.

Describe one experiment in which the glass transition temperature and melting temperature of a totally amorphous thermoplastic material can be determined. show the relevant experimental results in a diagram which should be properly annotated with the two temperatures clearly marked. what is likely to happen to the curve in the diagram if the amorphous polymer is replaced by a thermosetting type?
