Daya pompa air dibanding daya kipas angin adalah 5:3. Jika kedua alat digunakan rata - rata 4 jam perhari dan dalam 1 bulan memerlukan energi listrik 48 kwh, daya pompa dan daya kipas angin masing-masing adalah...disertai caranya ya..

Dik. misalkan pompa = p kipas = k Pp / Pk = 5 / 3 W = 48 kWh t = 4.30 = 120 h/bulan Dit. daya pompa................? daya kipas.............?
penyelesaian : Pp = (5/3) Pk W = (Pp + Pk). t W = ( (5/3)Pk + Pk). t 48 kWh = (8/3) Pk . (120 h) (8/3) Pk = (48 kWh) / (120 h) (8/3) Pk = 0,4 kW = 400 W Pk = (3/8). (400W) = 150 W Pp = (5/3). (150 W) = 250 W jd, daya pompa 250 W dan daya kipas 150 W

P = daya W = Besar Energi = 48 Kwh = 48000 wh T = Waktu = 4 jam x 30 hari = 120 jam
P = w/t P = 48.000 / 120 = 400 watt
5 : 3 = 8
Pompa Air = 5/8 x 400 = 250 watt Kipas Angin 3/8 x 400 = 150 watt
misalkan
pompa = p
kipas = k
Pp / Pk = 5 / 3
W = 48 kWh
t = 4.30 = 120 h/bulan
Dit. daya pompa................? daya kipas.............?
penyelesaian :
Pp = (5/3) Pk
W = (Pp + Pk). t
W = ( (5/3)Pk + Pk). t
48 kWh = (8/3) Pk . (120 h)
(8/3) Pk = (48 kWh) / (120 h)
(8/3) Pk = 0,4 kW = 400 W
Pk = (3/8). (400W) = 150 W
Pp = (5/3). (150 W) = 250 W
jd, daya pompa 250 W dan daya kipas 150 W
W = Besar Energi = 48 Kwh = 48000 wh
T = Waktu = 4 jam x 30 hari = 120 jam
P = w/t
P = 48.000 / 120 = 400 watt
5 : 3 = 8
Pompa Air = 5/8 x 400 = 250 watt
Kipas Angin 3/8 x 400 = 150 watt
