Extracted text: Solve for Prandtl (Pr) and Reynolds (Re) numbers depending on type of flow: A lead pipe has 2 cm inside diameter, 3 cm outer diameter, length of 130 cm. Liquid water at 4°C flows through the pipe. Air is blown around the outside of the pipe at 20 deg C. The inside wall of the said pipe has a temperature of 8 deg Celsius. Density of liquid water= 999.6509 kg/m³ Cp=4.218 kJ/kgK Viscosity of liquid water= 1.6193x10-3 Pa.s K (thermal conductivity of water) = 0.5742 W/mK
