Theoretical field capacity
WebbThe theoretical field capacity will be led from the following equation. TFC = Wt * Vt * K Eq. 2 - 6 Where, We use unit-1 system normally, therefore theoretical field capacity is shown as follows. TFC = Wt * Vt * 0.1 Eq. 2 - 7 Assume the field, which area is A (ha) and width is equal to Wt (m). WebbTheoretical field capacity is the rate of performance obtained if a machine performs its function 100% of the time at a given operating speed using 100% of its theoretical width. …
