Extracted text: correct number of significant figures. 2.26. WP The Prandtl number, Npr, is a dimensionless group important in heat-transfer calculations. It is defined as C,e/k, where C, is the heat capacity of a fluid, µ is the fluid viscosity, and k is the thermal conductivity. For a particular fluid, C, = 0.583 J/(g : °C), k = 0.286 W/(m °C), and u (remember, it is dimensionless), showing your calculations; then determine it with a calculator. 1936 lbm/(ft · h). Estimate the value of Np, without using a calculator Answer 2.27. The Reynolds number is a dimensionless group defined for a fluid flowing in a pipe as Re Dup/μ where D is pipe diameter, u is fluid velocity, p is fluid density, and u is fluid viscosity. When the value of the Reynolds number is less than about 2100, the flow is laminar-that is, the fluid flows in smooth streamlines. For Reynolds numbers above 2100, the flow is turbulent, characterized by a great deal of agitation. Liquid methyl ethyl ketone (MEK) flows through a pipe with an inner diameter of 2.067 inches at an average velocity of o.48 ft/s. At the fluid temperature of 20°C the density of liquid MEK is o.805 g/cm3 and the viscosity is o.43 centipoise [ 1 cP = 1.00 x 10¬³ kg/(m · s)]. Without using a calculator, determine whether the flow is laminar or turbulent. Show your -3 calculations.
