A miniature heat sink heat exchanger is constructed with circular cross section channels (similar to that in Example 7.4), each of which has a diameter of 3.0 mm, drilled through a rectangular block. Cooling water at 20°C flows at the rate of 0.5 kg/h through each circular pipe, which has a constant surface temperature of 80°C. Assuming fully developed velocity and temperature distribution conditions, determine the length of the drilled pipe if the outlet water temperature is 60°C. Also, based on your calculations, verify the fully developed condition assumption.

GIVEN • Heat exchanger constructed with circular cross section channels. • Diameter of channel (Di)= 3 mm = 3*10-3 m • Cooling water inlet temperature (Tin)= 200C • Cooling water flow rate (m• )=0.5 kg/h = 1.39*10-4 kg/s • Cooling water outlet temperature (Tout)= 600C • Surface temperature(Ts)=800C FIND (a) Length of the drilled pipe. (b) Verify fully developed condition assumption PROPERTIES AND CONSTANTS or Water at 60°C: Density (?) = 982.8 kg/m3 Specific heat (cp) = 4182.8 J/(kg K) Thermal conductivity (k) = 0.657 W/(m K) Absolute viscosity (?) = 483.7 × 10–6 (Ns)/m2 Prandtl Number (Pr) = 3.02
