Sebuah pipa tembaga panjang 2 m dengan suhu 25°C - 50°C dgn koefisien muai panjang 0,000017/°C ,maka panjang pipa setelah dipanaskan adalah?
Zuhh
Dik : L0 = 2 M T0 = 25 C T = 50 C α = 0,000017/C dit : L ?
DIJWB : L = L0 x (1 + α x ΔT) = 2 x (1 + 0,000017 x (50-25) = 2 x (1+ 0,000017 x 25) = 2 x 1 + 0,000425) = 2,00085 m

L = 2 m, T awal = 25°C, T akhir = 50°C, koefisien muai panjang = a = 0,000017/°C T = T akhir - T awal = 50 - 25 = 25°C L' = L + l l = L x a x T l = 2 x 0,000017 x 25 l = 0,00085 m L' = L + l = 2 + 0,00085 = 2,00085 m
L0 = 2 M
T0 = 25 C
T = 50 C
α = 0,000017/C
dit : L ?
DIJWB :
L = L0 x (1 + α x ΔT)
= 2 x (1 + 0,000017 x (50-25)
= 2 x (1+ 0,000017 x 25)
= 2 x 1 + 0,000425)
= 2,00085 m
T = T akhir - T awal = 50 - 25 = 25°C
L' = L + l
l = L x a x T
l = 2 x 0,000017 x 25
l = 0,00085 m
L' = L + l = 2 + 0,00085 = 2,00085 m
