Essays on Flow Velocity

Abstract

The experiment was done to investigate the relative roughness of pipe three though a plot of the friction factor verses the Reynolds number. A comparison of the obtain results was made against a Moody diagram. Also, additional comparison of the experimental results obtained from pipe 1 and 2 were made against theoretical values obtained through Prandtl and Blasius equations. This process entailed plotting the theoretical and the experimental values on the same comparative roughness against Reynolds number chart. Additional results of different types of flow, exhibited by the flowing fluid, was done and represented in a graph of head ...

Fluid Mechanics is a branch of engineering study and it deals with various properties of fluids. In our daily life we use various types of fluids. Most of the fluids are readily available and have some excellent properties. Significance of Fluid mechanics is to know how the fluids and its various properties can be used in our daily life. This part of engineering is integral part of main stream engineering like Civil Engineering, Mechanical Engineering as well as Chemical Engineering as these brunches of engineering often deals with fluid. In this essay various aspects of fluid mechanics and its application ...

One of the main problems of classical mechanics is that of turbulent fluid flow. The reason for this is that there is the presence of thin no-slip boundary which requires a lot of meshpoints in order for the solution to be arrived. There is a research which has been arrived and researched upon which shows that with the use of slip boundary condition to be the model for friction to be achieved for the small skin, there is the possibility for predictive simulation for mean quantities. An example of such mean quantities is the drag and lift turbulent flow with millions ...

Introduction

The term migraine refers to a chronic neurological disorder characterized by persistent moderate to severe headaches that are usually linked to various autonomic nervous system symptoms. A typical case of migraine presents itself as a pulsating headache that affects only one side of the head for a period of two to seventy two hours. Within this period, the patient displays symptoms such as photophobia, vomiting, nausea and phonophobia. There are four documented sequential phases of a migraine i.e. the prodrome phase (1), aura phase (2), headache/ pain phase (3) and prodrome phase (4). Analgesics such as nonsteroidal anti-inflammatory drugs are normally administered ...

1. A 55 gal. drum of organic solvent, full and sealed, weighs 400 lbs. The empty drum weights 40 lbs. What is the density of the solvent, in kg/L? What is its specific gravity? Variables: Vdrum = 55 gal. = 0.208 m3 mempty = 40 lbs = 18.14 Kg mfull = 400 lbs = 181.44 Kg msolvent = ? ρsolvent = ? Relationships: msolvent = mfull – mempty

ρ = m/V Computation: msolvent = 163.29 Kg ρsolvent = msolvent/Vdrum = 163.29Kg/0.208m3 = 785.05 Kg/m3

2. A cylindrical object 0.5m in diameter and 2m long weights has a mass of 200kg. The object is floating end-down ...
