The table above contains 10 measurements taken of the volume flow rate through a pump running at a fixed operating conditions. Find the following statistical quantitie for this data set: a. The average flow rate: Vave liters/hr. b. The median flow rate: Vmedian liters/hr. c. The sample standard deviation: 0, liters/hr.
A) An experimental text program is being set up to calibrate a new flow meter. The flow meter is to measure the mass flow rate of liquid flowing through a pipe. It is assume the mass flow rate (m) is a function of the pressure difference (AP)across the meter, diameter of the pipe (D), viscosity of the fluid (μ), and the density of the fluid (p). Using the dimensionless analysis, find the-groups for this case study.
a) Vortex shedding is a common fluid flow problem across bluff bodies. The design of buildings and bridges take into account the analysis of vortex shedding phenomena to avoid the occurrence of resonance, where the natural frequency of the body matches the vortex shedding frequency. In this analysis, the following parameters are found to be important: velocity of flow (V), density of fluid (p), hydraulic diameter of the duct (D₁), dynamic viscosity of fluid (u), width of body (B) and the vortex shedding frequency (n). Using the method of repeating variables, find the non-dimensional relationship governing the phenomena.
The conduction heat transfer in an extended surface, known as a fin, yields the following equation for the temperature T, if the temperature distribution is assumed to be one-dimensional in x, where x is the distance from the base of the fin, as shown in figure: To Fin >X T(x) h,T Heat Loss d²T_hp (T-T) = 0 dx² ΚΑ dT dx = 0 Here, p is the perimeter of the fin, being 2R for a cylindrical fin of radius R; A is the cross-sectional area, being R2 for a cylindrical fin; k is the At x = 0: T = T₁ dT At x=L: :0 dx thermal conductivity of the material; T is the ambient fluid temperature; and h in the convective heat transfer coefficient.

Given: Pi constant to be used: 3.14159 Capillary tube: radius = 0.02 cm; length = 9 cm; pressure = 0.7 mmHg Liquid sample: density = 4 ml; time of flow = 4.5 seconds Ans. the ff questions. •What is the pressure in MKS unit? •What is the pressure in CGS unit? •What is the viscosity of the liquid? • If the weight was given as 8.5 grams, what will be the density of the liquid? •What is the kinematic viscosity of the liquid? •What is the fluidity of the liquid?
Ql: The viscosity in industrial measurement continue to use the CGS system of Lunits, since centimeters and grams vield convenient numbers for many fluids. The absolute viscosity () unit is the poise, I poise = 1 gtem. s). The kinematic viscosity (v) unit is the stohes, I stokes = 1 em /s. Water at 20C has u = 001 poise and also V= 0.01 stokes. Express these resalts in (a) SI and (h) BG tanits.

Construct a plot showing the sequence of events on an oil viscosity vs. pressure for the given reservoir below. A reservoir was discovered in an undersaturated condition (call this state, point A). Gas was injected to maintain pressure (point B), and eventually formed a secondary gas cap (point C). Water injection was employed to increase the reservoir pressure (above discovery pressure) until an undersaturated condition existed again (point D). Finally, all injection ceased and the reservoir was blown down to abandonment pressure (point E).
