LAMPIRAN A PERHITUNGAN A.1 Kalibrasi Tangki

Mencari debit aliran Q = ^V

t

= ^{1,97 ft}

5 s

= 0,394 ft³/s

A.2 Perhitungan Pipa ³⁄₄ dengan Skala 3 1. Menghitung Nilai ΔP

P1 = ρ × g × h1

= 62,245 lb ft³

⁄ × 32,174 ft s⁄² × 1,721 ft

= 3,447 lb ft.s⁄ ² P2 = ρ × g × h2

= 62,245 lb ft³

⁄ × 32,174 ft s⁄² × 2,812 ft

= 5631,51 lb ft.s⁄ ² ΔP = P2 – P1

= 5631,51 lb ft.s⁄ ² – 3,447 lb ft.s⁄ ²

= 2184,91 lb ft.s⁄ ²

2. Menghitung Panjang Ekivalen

Standar Tee = 5 × 4,9 ft = 24,5 ft Standar Elbow = 3 × 2,3 ft = 6,9 ft

Kran = 5 × 25 ft = 125 ft +

Le = 156,4 ft

3. Menghitung Persamaan Debit (Q) Q = ^{ΔP × π × D}

=

2184,91 lb⁄ft.s² × 3,14 × 0,0443 ft⁴ 128 × 0,00054 lb⁄ft.s² × 156,4 ft

= 0,002444 ft³⁄s

4. Mencari Luas Permukaan Pipa A = ^{π ×D}

4

= 3,14 × 0,0443 ft² 4

= 0,0015 ft²

5. Mencari Kecepatan Aliran V = ^Q

A

= ^{0,0024 ft}

3⁄s 0,0015 ft²

= 1,5865 ft⁄s

6. Mencari Bilangan Reynold Re = ^{ρ × V × D}

µ

=

62,245 lb ft³

⁄ × 1,5865 ft s⁄ × 0,0443 ft 0,00054 lb ft.s⁄

= 8101,69114

7. Mencari Faktor Friksi (f) f = Kekasaran Pipa

Diameter

= _{0,0443 ft}^0,00015 = 0,0033 ft

8. Mencari Nilai Head Loss F = 2 × f × Le × v²

D ×g

= 2 × 0,0033ft × 156,4 ft × 1,5865² ft s⁄ 0,0443 ft × 32,174ft s⁄

= 1,8705 ft

9. Mencari Kesetimbangan Energi W = ^ΔP

ρ × g+ F

=

2184,91 lb ft.s²

⁄

62,245 lb.ft³ × 32,174 ft⁄s²

+
