Aone shell and two tube type heat exchanger has an overall heat transfer coefficient of 350 btu/h · ft2 · °f. the shell side fluid has a capacity rate of 25,000 btu/h · °f, while the tube side fluid has a heat capacity rate of 50,000 btu/h · °f. the inlet temperature on the shell side and tube side are 250°f and 100°f, respectively. if the total heat transfer area is 150 ft2, determine the following: the heat transfer effectiveness. the actual heat transfer rate in the heat exchanger

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.

If a particle moves along a path such that r : (3 sin t) m and ? : 2t rad, where t is in seconds. what is the particle's acceleration in m/s in 4 seconds? a)- 16.43 b)- 16.29 c)- 15.21 d)- 13.79

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.
