A 240 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 180 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 $100 per hour and the operator's wage is $20.00 per hour plus 40% for fringes, insurance, and worker's compensation.

Applied Fluid Mechanics

A fluid is a substance that is continuously deformed by the application of shear stress. The rate of deformation of a fluid depends on its viscosity. The fluid tries to flow when it interacts with some other system.
