CALCULATION :-
• Area of pipe = A = 2.01 x 10-4 m2
• Discharge
= Q = 5 / (t x 1000)
• Pressure head loss of water hf = P in bar x 10
=
(m)
• Velocity = V = Discharge rate / Area
= V = Q/A
• Coefficient of friction

Exp. 3: Thermal conductivity of metal
To determine temperature gradient in aluminium rod and calculate the conductive heat
transfer rate in the rod.
𝑸̇ = K A ΔT/ L
𝑄̇=Q/t – Heat transfer rate
K- Coefficient of thermal conductivity of the material.
A – Area of cross section. Given = 4.91 × 10−4 𝑚2
ΔT - Temperature difference between two sections( ∆t)
L - Length of the rod
