The Pelton wheel is a water impulse turbine. It was invented by Lester Allan Pelton in the 1870s. The Pelton wheel extracts energy from the impulse of moving water‚ as opposed to its weight like traditional overshot water wheel. Although many variations of impulse turbines existed prior to Pelton ’s design‚ they were less efficient than Pelton ’s design; the water leaving these wheels typically still had high speed‚ and carried away much of the energy. Pelton ’s paddle geometry was designed so that

Lab Report: DRILLING FLUID (MUD) DENSITY Objective: The aim of this experiment is to determine the mud density‚ specific gravity and hydrostatic pressure gradient for water-based-mud‚ WBM (Drilling fluid) using the OFITE mud balance. Theory: Drilling fluids are used during the drilling of boreholes‚ either for oil wells or water boles holes. One of the major functions of a drilling fluid includes providing hydrostatic pressure to prevent formation fluids from entering the wellbore. To ensure

To be a pneumatic technician‚ one must go through around two years of training. Training for the job is hands-on because one will not know how to properly work a pneumatic system without experience working the pneumatic system. When training is completed‚ the Fluid Power Society‚ or FPS‚ gives the graduate credit and a completion certificate. The average annual salary for a

APPARATUS: The Jet Impact Apparatus Volumetric Hydraulic Bench/Water 3 different shapes of vanes; Flat Plate‚ Conical Cup‚ and Hemispherical Cup Stop Watch 1. INTRODUCTION One way of producing mechanical work from fluid under pressure is to use the pressure to accelerate the fluid to a high velocity in a jet. The jet is directed on to the vanes of a turbine wheel‚ which is rotated by the force generated on the vanes due to the momentum change or impulse which takes place as the jet strikes the

The lumbar puncture revealed that Nancy had meningitis. Meningitis is caused by an infection of the cerebrospinal fluid resulting in inflammation of the meninges. 1. What are the meninges? They are three membranous layers that surround the brain and spinal cord. 2. Name the meningeal layers that surround the

spinal cord is exposed to amniotic fluid during fetal life. Amniotic fluid is the watery fluid within the innermost membrane that encloses the embryo and surrounds the fetus throughout pregnancy. Amniotic fluid is also what cushions the fetus protecting it from injury‚ providing freedom of fetal movements‚ helping maintain the fetal oxygen supply and helping stabilize temperature. The composition of the fluid changes over the course of gestation. Initially‚ amniotic fluid is similar to maternal plasma

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.

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
