Tonne per Day (t/day)

Tonnes per day (TPD) state the capacity of chemical plants, sugar mills (tonnes of cane crushed per day), cement kilns and solid-waste facilities.

Symbol: t/day

Quantity: mass flow rate ṁ

SI relation: 1 t/day = 0.01157407407407 kg/s (exact)

Derivation: 1 t/day = 1000/86,400 kg/s.

Exact: yes, by definition

Typical uses

Chemical and fertiliser plant capacity
Sugar mill TCD and cement kiln output
Municipal solid waste generation
