You have just bought a used track-type tractor to add to your production fleet. the initial capitalized value of the tractor is $110,000. the estimated service life remaining on the tractor is 10,000 hours and the anticipated operating conditions across the remainder of its life are normal. the salvage value of the tractor is $12,000. the tractor was purchased on july 1, 1997.a. what amount of depreciation will you claim for each calendar year between 1997 and 1998? b. what percent of the total depreciable amount is taken in the first year?

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.

Refrigerant 134a enters an insulated compressor operating at steady state as saturated vapor at -26°c with a volumetric flow rate of 0.18 m3/s. refrigerant exits at 9 bar, 70°c. changes in kinetic and potential energy from inlet to exit can be ignored. determine the volumetric flow rate at the exit, in m3/s, and the compressor power, in kw.
