1.The water content in one of five standard Proctor test samples is 15.2%. The corresponding degree of of saturation is 85%. Calculate the dry unit weight if Gs=2.67
2.The cost of a 620 ft3/hr process unit is $920,000. From historical cost records, the capacity ratio exponent of a process unit is 0.5. Use the capacity ratios raised to an exponent method to determine the estimated cost of a similar process unit with a capacity of 310 ft3/hr.
