Total volume of a cylinder shaped tank is the area, A, of the circular end times the length, l. A = π r 2 where r is the radius which is equal to 1/2 the diameter or d/2. Therefore: V(tank) = π r 2 l Calculate the filled volume of a horizontal cylinder tank by first finding the area, A, of a circular segment and multiplying it by the length, l.

($30,000 Fixed costs + $50,000 variable costs) ÷ 10,000 units = $8 cost per unit. In the following month, ABC produces 5,000 units at a variable cost of $25,000 and the same fixed cost of $30,000. The cost per unit is: ($30,000 Fixed costs + $25,000 variable costs) ÷ 5,000 units = $11/unit. Related Article. How to Calculate Unit Product Cost

As noted above, weight refers to mass (i.e., measured on a balance). When examining the equation for each of the percent solutions above, it is very important to note that in all cases the denominator refers to the solution mass or volume and not just the solvent mass or volume. Thus, solution mass is the combined mass of solute and solvent, and solution volume …
A 20,000-tonne chrome ore cargo sitting in port at a demurrage charge of $40,000 a day for even five days would mean $200,000 in additional costs, or $10 per tonne, a chrome alloy trader said. Rising fuel costs have also continued to contribute to higher chromite prices, sources told Fastmarkets.
