Fluid intelligence reflects information processing capabilities‚ reasoning‚ and memory. It is used to evolve the ability to think clearly. For instance‚ a person who is asked to arrange a series of letters according to some rule or to memorize a set of numbers uses fluid intelligence. Although it is defined as the inmate and learning caoacity of all individuals. To my knowledge fluid intelligence is used in so many ways‚ throughout the country. It normally affect’s children during childhood and

ENT 310 Fluid Mechanics Midterm #1 – Open Book and Notes Name _______________________ 1. (5 pts) The maximum pressure that can be developed for a certain fluid power cylinder is 50.0 MPa. Compute the force it can exert if its piston diameter is 100 mm. 2. (5 pts) Calculate the weight (in Newtons) of 100 liters of fuel oil if it has a mass of 900 Kg. 3. (5 pts) The fuel tank of a truck holds 0.20 cubic meters. If it is full of gasoline having a specific gravity of 0.68‚ calculate the weight

1. Using diagrams and/or graphs‚ explain the following terms: a. Pressure Head pressure head [′presh·ər ‚hed] (fluid mechanics) Also known as head. The height of a column of fluid necessary to develop a specific pressure. The pressure of water at a given point in a pipe arising from the pressure in it. b. Total Discharge Head Total discharge head refers to the actual physical difference in height between the liquid level in the pit and the highest point of the discharge pipe or water level in

I. Lubricants selection and Application A.Viscosity Most important property of any lubricant is viscosity. A common mistake when selecting a grease is to confuse the grease consistency with the base oil viscosity. Because the majority of grease-lubricated applications are element bearings‚ one should consider viscosity selection for those applications. While most would not use an EP 220 gear oil for an oil-lubricated electric motor bearing‚ many people will use a grease containing that same oil

CBE 6333‚ R. Levicky 1 Potential Flow Part I. Theoretical Background. Potential Flow. Potential flow is frictionless‚ irrotational flow. Even though all real fluids are viscous to some degree‚ if the effects of viscosity are sufficiently small then the accompanying frictional effects may be negligible. Viscous effects become negligible‚ for example‚ for flows at high Reynolds number that are dominated by convective transport of momentum. Thus potential flow is often useful for analyzing external

MEASURING AND MODELLING HYDRAULIC FLUID DYNAMICS AT HIGH PRESSURE - ACCURATE AND SIMPLE APPROACH. International Journal Of Fluid Power‚ 13(2)‚ 51-59. ASTRACT: Dynamic properties of hydraulic fluids have to be taken into account in ever increasing fluid power applications. The main reasons are increasing accuracy demands in control and modeling‚ as well as increasing operating pressure and temperature ranges. Moreover‚ the already wide spectrum of different hydraulic fluids is also expanding all the time

FLUID MECHANICS Fluids mechanics is a branch of mechanics that is concerned with properties of gases and liquids. Mechanics is important as all physical activities involves fluid environments‚ be it air‚ water or a combination of both. The type of fluid environment we experience impacts on performance. Flotation The ability to maintain a stationary on the surface of the water- varies from he on person to another. Our body floats on water when forces created by its weight are matched equally

Fluid Report 2 In the derivation of Bernoulli’s equation‚ the assumption of the inviscid and incompressible flow is used. However in the real case‚ the viscosity cannot be neglect and the density of the flow is not always constant. Thus Bernoulli’s equation is not always correct. For the lab‚ it is reasonable to assume the flow is inviscid and incompressible. Firstly‚ the pitot was placed at the center of the flow. The skin friction (effect of viscosity) is inversely proportional to distance
