LAMPIRAN I KETIDAKPASTIAN DAN DATA HASIL PENGUJIAN

1. KETIDAKPASTIAN Diambil contoh pada kondisi turbin angin: -

Sudu

: NACA 0012

-

Jumlah sudu

: 3 buah

-

Beban

: 10 W

-

Sudut pitch

: 00

dengan data hasil pengujian sebagai berikut: -

Tegangan (V) : 10.18 Volt

-

Arus (I)

: 0.401 Ampere

-

Putaran (n)

: 26.6 rpm

-

Kecepatan angin (V∞) : 3.85 m/s

Ketidakpastian alat ukur: -

Anemometer : ± 3 %

-

Tachometer

: ± 0.05 %

-

Multimeter

: AC. Voltage : ± 1.2 % AC. Current : ± 1.5 %

Ditanya: 1. Ketidakpastian daya angin ? 2. Ketidakpastian daya turbin ? 3. Ketidakpastian tip speed ratio (TSR) ? 4. Ketidakpastian efisiensi turbin ?


1. Ketidakpastian daya angin Kecepatan angin (V∞) = 3.85 m/s  δV∞ = 3.85 x 3 % = 0.1155 m/s Massa jenis udara

ρ = 1.1594 kg/m3

Diameter turbin

D = 1.5 m

Tinggi turbin

H = 1.5 m

Luas sapuan rotor

A = 1.5 x 1.5 = 2.25 m2

Maka, = ½ ρ A (δV∞)3 = ½ (1.1594)(2.25)(0.1155)3 = 0.002009 Watt Ketidakpastian daya angin adalah = ½ ρ A V∞3 ± 0.002009

Pa

= 74.44 ± 0.002009 = 74.44 ± 0.0026 % 2. Ketidakpastian daya turbin Tegangan (V) = 10.18 Volt  δV = 10.18 x 1.2 % = 0.1221 Volt Arus (I) = 0.401 Amp  δI = 0.401 x 1.5 % = 0.006015 Amp Efisiensi generator ƞg = 0.7 Maka, = (δV. δI)/ ƞg = (0.1221)(0.006015)/0.7 = 0.001049 W Ketidakpastian daya turbin adalah Pt = V.I / ƞg = (10.18)(0.401)/0.7 ± 0.001049 = 5.83 ± 0.001049 = 5.83 ± 0.0179 %


3. Ketidakpastian tip speed ratio (TSR) Putaran (n) = 26.6 rpm  δn = 26.6 x 0.05 % = 0.0133 rpm = 2π δn/60 = 2(3.14)(0.0133)/60 = 0.00139 rad/s Wλ =

.r/δV∞

= (0.00139)(0.75)/0.12 = 0.00868 Ketidakpastian tip speed ratio (TSR) λ = ω.r/V∞ ± 0.00868 = 0.52 ± .00868  = 0.52 ± 1.66 % 4. Ketidakpastian efisiensi turbin angin Pt = 5.83 ± 0.001049  (5.8289 – 5.8310) Pa = 74.44 ± 0.002009  (74.4379 – 74.4420) Untuk nilai minus (-) ηt = (5.8289/74.4379 ) x 100 % = 7.8305 % Untuk nilai positif (+) ηt = (5.8310/74.4420) x 100 % = 7.8329 % Selisihnya: Wηt = 7.8329 – 7.8305 = 0.0024 % Maka ketidakpastian efisiensi turbin angin adalah: ηt = {(5.83/74.44)x100%} ±0.0024% = 7.8318 % ± (0.0024 %) = 7.8318 % ± 0.0306 %
