Ifomula yokubala yamandla yesithando sokushisa sokungeniswa

1. Ukubalwa kwamandla okushisisa kwesithando sokungenisa ngaphakathi P=(C×T×G)÷(0.24×S×η) Amanothi esithando somlilo:

1.1C = Ukushisa okukhethekile kwento (kcal/kg℃)

1.2G = Isisindo sengcezu yokusebenza (kg)

1.3T=izinga lokushisa elishisayo (℃)

1.4 t=isikhathi (S)

1.5η = Ukushisa kahle (0.6)
