Perhitungan
1. Pompa turbine
Kecepatan 4 data ke 3
V = 30 liter/detik
t = 117.78 detik
T = 0.59 N.m
n = 691.3 rpm
hvacum = -0.25
hturbine = 0.5
H = hturbine - hvacum = 0.75 m
Daya (P) = 2πnT
60
= 2x 3.14 x ( 27
14 ) x691.3 x 0.59
60 = 82.3309 watt
Debit (Q) = Vt
= 30
117,78 = 0.254 liter/det
Efisiensi (ŋ) = ρ x g x H xQ x10−3P x 100%
= 966 x9.79 x 0.75 x0.254 x 10−382.3309 x 100%
= 2.15 %
Kecepatan 4 data ke 4
V = 40 liter/detik
t = 159 detik
T = 0.59 N.m
n = 693.1 rpm
hvacum = -0.25
hturbine = 0.5
H = hturbine - hvacum = 0.75 m
Daya (P) = 2πnT
60
= 2x 3.14 x ( 27
14 ) x693.1 x 0.59
60 = 82.5452 watt
Debit (Q) = Vt
= 40
159 = 0.251 liter/det
Efisiensi (ŋ) = ρ x g x H xQ x10−3P x 100%
= 966 x9.79 x 0.75 x0.251 x10−382.5452 x 100%
= 2.15 %
