Q.2 (from Street‚ Watters‚ and Vennard) The weight density γ = ρg of water in the ocean may be calculated from the empirical relation γ = γo + K(h1/2)‚ in which h is the depth below the ocean surface‚ K a constant‚ and

but surfactant is needed to regulate surface tension. Also surface tension promotes movement of fluids across the alveolar membrane‚ therefore the surfactant also regulates the movement of fluids. Attraction of the molecules in the fluid film within the alveoli is what causes surface tension. The water molecules have a higher attraction to each other than the air in the surrounding area causes the fluid film to take up the smallest area possible. Therefore as surface tension force increases alveoli

accurate measurement of mud density is made by using the Mud Balance. Viscosity is the resistance to flow offered by a fluid. The term is loosely applied as the flow properties of drilling mud. The relative viscosity‚ or the cuttings carrying ability of the drilling fluid‚ can be measured by the Marsh Funnel. This comparative measurement is performed by simply recording the number of seconds required for a given volume of drilling fluid to pass through the Marsh Funnel. Dean Bennett Supply is your

caused by a fluid jet on a horizontal plate and a hemispherical shell and compare it with the expected theoretical force. 2 Theory When a rubber ball strikes a solid surface it nicely rebounds from the solid surface. The amount of rebound would depend on the coefficient of restitution. However‚ when a steady fluid jet strikes a solid surface‚ it does not rebound. But‚ a stream of fluid is formed which moves over the surface and the fluid leaves the surface tangentially. If a fluid jet is impacting

FUNDAMENTAL CONCEPTS Heat transfer is energy in transit‚ which occurs as a result of temperature gradient or difference. This temperature difference is thought of as a driving force that causes heat to flow. The concepts of heat transfer and temperature‚ the key words in the discipline of heat transfer‚ are 2 of the most basic concepts of thermodynamics. dffffffffff rifffff orfff ffffffffff fv ing ff ce Rate of transport process= fffffffffff or rate = coefficient B driving force resist

Water Balance Adipose tissue is one of the most hydrated of all tissues in the human body. False The most abundant cation in intracellular fluid is sodium. False Electrolytes determine most of the chemical and physical reactions of the body. True Solutes‚ regardless of size‚ are able to move freely between compartments because water carries them along the osmotic gradients.False The thirst center in the brain is located in the hypothalamus.True Dehydration can be caused by endocrine disturbances

GENERAL PRINCIPLES OF DISORDERS OF WATER BALANCE (HYPONATREMIA AND HYPERNATREMIA) AND SODIUM BALANCE (HYPOVOLEMIA AND EDEMA) Literature review current through: Sep 2013. | This topic last updated: ene 15‚ 2013. 1. INTRODUCTION — The plasma sodium concentration is regulated by changes in water intake and excretion‚ not by changes in sodium balance. hyponatremia is primarily due to the intake of water that cannot be excreted hypernatremia is primarily due to the loss of water that has not

the test section. In the first method‚ the drag coefficient can be determined by directly measuring the drag force exerted on the cylinder. The drag force by weight measurement is given by the weight‚ which have to be added on the weight pan to balance the cylinder at air speed. In contrast‚ the second method was carried out by measuring the outlet dynamic pressure at different location in the exit plane along the transverse direction on the cylinder. A comparison was then made between the

Change in Pressure and Different Depths in a Static Fluid Lab Marcus Uchaker MET: 2050 January 26‚ 2012 Purpose: The purpose of this lab is to devise a correlation between that of the data we have collected from our experiment and compare it to that of theory. In this experiment 3 different tests were done in order to test this theory. The first test was to tie a balloon on the end of a manometer and measure the pressure at different depths in a large beaker filled with water. The next
