A240 hp (power-shift) dozer is used in a pushing operation. the dozer is equipped with a straight blade. the material (dry and noncohesive) weighs 98 pcf in the bank state. it is estimated the material will swell 6%, from bank to loose state. the center-of mass–to–center-of-mass pushing distance is 200 ft. job efficiency can be assumed to be equivalent to a 45-min hour. calculate the production in bcy per hour and the direct cost of the proposed earthmoving operation in dollars per bcy. the company's normal o& o cost for these machines is $95 per hour and the operator's wage is $15.00 per hour plus 40% for fringes, insurance, and worker's compensation. (207 bcy/hr, $0.561/bcy).

Liquid flows at steady state at a rate of 2 lb/'s through a pump, which operates to raise the elevation of the liquid 100 ft from control volume inlet to exit. the liquid specific enthalpy at the inlet is 40.09 btu/lb and at the exit is 40.94 btub. the pump requires 3 btu/s of power to operate. if kinetic energy effects are negligible and gravitational acceleration is 32.174 tt/s, the heat transfer rate associated with this steady state process is most closely 1)-2,02 btu/s from the liquid to the surroundings 2)-3.98 btu/s from the surroundings to the liquid. 3)-4.96 btu/s from the surroundings to the liquid. 4)-1.04 btu/s from the liquid to the surroundings.
