For the system form of the basic laws, the momentum of a system can change as a result of: a. pressure acting on the system. b. friction acting on the system. c. gravity acting on the system. d. body forces acting on the system. e. surface forces acting on the system. f. all of the above.

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.

Apump is used to circulate hot water in a home heating system. water enters the well-insulated pump operating at steady state at a rate of 0.42 gal/min. the inlet pressure and temperature are 14.7 lbf/in.2, and 180°f, respectively; at the exit the pressure is 60 lbf/in.2 the pump requires 1/15 hp of power input. water can be modeled as an incompressible substance with constant density of 60.58 lb/ft3 and constant specific heat of 1 btu/lb or. neglecting kinetic and potential energy effects, determine the temperature change, in °r, as the water flows through the pump.

Acompressor receives the shaft work to decrease the pressure of the fluid. a)- true b)- false
