Chapter 9, Problem 10RQ
- 10. The Peclet number is used in heat transfer in general and forced convection calculations in particular. It is a function of the two other dimensionless groups, the Reynolds number and the Prandtl number. Determine the functional form of these dimensionless groups, using Rayleighʼs method. The problem depends on the following variables:
| ρ = Liquid density | [=] kg/m3 |
| Cp = Specific heat of liquid | [=] J/(g oC) |
| µ = Liquid viscosity | [=] kg/(m s) |
| a = Thermal diffusivity | [=] m2/s |
| k = Thermal conductivity of the plate | [=] W/(m oC) |
| x = Distance from edge of the plate | [=] m |

Important variables in a particular water machine are: Fluid density (ρ), impeller angular velocity (ω), impeller diameter (D), volume flow rate (), fluid viscosity (µ), head (gH). In fact, (gH) shows the energy that the fluid unit mass receives from or gives to the machine, independent of gravitational acceleration (g). Therefore, gH value is used instead of H. Important sizes in terms of the operation of the water machine are power (P), (gH) and efficiency ( h). Derive dimensionless numbers by typing these two parameters based on the above variables and applying Buckingham's p method (repeating variables method).
Consider the following equation. All three of the terms in parentheses are dimensionless groups. Because kC is difficult to determine directly, the other variables are measured and kC is calculated from the given equation.
What is the estimated value of kC? What are the units of kC? Show your work. The following values were measured: D = 8.0 mm, DAB = 0.475 cm2/s, μ = 1.12 x 10–3 N-s/m2, ρ = 1.00 x 10–3 g/cm3, v = 15.0 m/s.

- The Reynolds number is a dimensionless group defined as follows for a liquid that flows through a pipe: Re = Dvρ / μ where D is the diameter of the pipe, v is the velocity of the fluid, ρ is its density and µ its viscosity. When the Reynolds number value is less than 2100, the flow is laminar, that is, the liquid it moves in lines of smooth flow. For Reynolds numbers greater than 2100, the flow is turbulent, characterized by considerable agitation.

- At any time, approximately 20 volcanoes are actively erupting on the Earth, and 50–70 volcanoes erupt each year. Over the past 100 years, an average of 850 people have died each year from volcano eruptions. As scientists and engineers study the mechanics of lava flow, accurately predicting the flow rate (velocity) of the lava is critical to saving lives after an eruption. Jeffrey’s equation captures the relationship between flow rate and viscosity as: where ρ is the density of the lava, g is gravity, t is the flow thickness, α is the slope, and m is the lava viscosity. Typical values are given as follows for the flow rate: m= 4x103 kg/(m.s) ±1% ρ= 2.5 g/cm3 ±1% t= 28 cm ±0.5 cm α= 10° ±1 ° g= 9.81 m/s²arrow_forwardThe power P required to drive a propeller is known to depend on the diameter of the propeller D, the density of fluid ρ, the speed of sound a, the angular velocity of the propeller ω, the freestream velocity V , and the viscosity of the fluid µ.
