### How To Calculate Production Capacity | Bizfluent

Nov 21, 2018 The first step in understanding production capacity is to calculate the machine-hour capacity of the factory or manufacturing plant. For example, say that a plant has 50 machines and workers can use the machines from 6 a.m. until 10 p.m., or for 16 hours a day. The daily plant capacity in hours is 16 hours multiplied by 50 machines, or 800 ...

Then its capacity considered is ( (1x10)/0.04125) = 242.4242 m 3 / day. That means, a hydraulic excavator can excavate 242.4242 m 3 of soil in one day. Its cost per day including driver and fuel is Rs. 5000. Then the cost of 10m 3 of excavation can be calculated as: No. of days required for 10m 3 excavation = 10/242.4242 = 0.04125 days.
