Pressure and buoyancy 11-12-99 sections 101 - 106 what is a fluid when we talk about atmospheric pressure, we're talking about the pressure exerted by the weight of the air above us the air goes up a long way, so even though it has a low density it still exerts a lot of pressure: a basketball floats in a bathtub of water the ball. Basketball sizes vary depending on the league or governing body for a particular basketball game basketballs are measured by circumference, inflation pressure or weight according to usa basketball, balls should be made of leather or synthetic leather. 1 science 1206 unit 2: weather dynamics worksheet 8: north american weather systems air mass is a large body of air which the temperature and moisture content at a specific attitude are fairly uniform front: the leading edge of a moving air mass air masses with difference properties don’t blend easy, so a boundary, or front, develops as they meet. Get your basketball and measure the air pressure inside of it using the pressure gauge change pressure accordingly to what pressures you want to measure when the basketball reads the correct pressure, measure one meter from the floor because this will be the height that you drop the ball from.
Dynamics of low-pressure and high-pressure fuel cell air supply system1 sylvain gelﬁ2, anna g stefanopoulou3, jay t pukrushpan, huei peng automotive research center university of michigan, ann. The dynamic pressure is about 62 psi, so of the 100 psig total pressure, 938 psig is static pressure in a 25-inch pipe for the extremely high velocity scenario, the 47 ft/sec velocity results in 15 psi of dynamic pressure and 85 psig of static pressure. Dynamic pressure is the additional pressure of a fluid that would hit an area and would be forced to consume completely it's kinetic energy it is expressed by the relation: p dynamic= rho(v^2/2. The effects of air pressure on a basketballs' bounce by julia o'brien and katherine simon in conclusion, our hypothesis was right and the ball bounced higher when there was more air pressure in the ball when the air pressure was released by small amounts at a time the height was shortened gradually.
A regulation nba air pressure in a basketball basketball must contain between 7 1/2 and 8 1/2 pounds of pressure per square inch what is the official air pressure inside of a basketball what is the official air pressure inside of a basketball. What is the proper air pressure for various sports balls update cancel answer wiki 3 answers akua ova, founder of team 2four, how much air pressure should a basketball have given the regulation ball air pressure range is 85-15 lbs/sq in, what is the air pressure used for the balls in this world cup. In this experiment you will test if air pressure will affect the dynamics of ball bouncing share your story with science buddies under pressure: ball bouncing dynamics you will use an air pump, a basketball, and an air pressure gauge to test if changing the air pressure will change the bounciness of the ball.
Science fair project my project was to determine if too much air in a basketball affects a player’s performance too little or too much air can definitely affect a player’s performance i thought that the more the air pressure the better the dribble. A basketball's bounce is what makes it such a great play item measuring the effects of air temperature on the bounce of a basketball can reveal a lot about air pressure. Air - dynamic and kinematic viscosity - online calculator, figures and tables showing dynamic (absolute) and kinematic viscosity of air at temperatures ranging from -100 to 1600°c (-150 to 2900°f) at pressure ranging from 1 to 10 000 bara (145 - 145000 psia) - si and imperial units. Measuring the effects of air temperature on the bounce of a basketball can reveal a lot about air pressure materials for this experiment you will need a basketball, an air pressure gauge, a ladder, a measuring stick, butcher paper, a marker, a video recorder and access to a thermostat. Air pressure allows your basketball to keep its round shape and remain hard and bouncy if air escapes from the ball, the pressure inside the ball changes air pressure is measured using psi, or pounds per square inch.
It's easier to get a sense of air and air pressure when you think of air that is contained within something, such as your basketball, an air mattress, or a bike tire air is composed of different gases, including nitrogen, carbon dioxide, water vapor, oxygen, and others. Joanne exerts a force on a basketball as she throws the basketball to the east which of the following the book has a greater mass than the feather and experiences less air resistance (b) the book has a greater mass than the feather and experiences a greater net force ap1 dynamics 1 1 1 1 1 1 = =. For a 295″ basketball (mens) and a 285″ basketball (womens), the recommended air pressure range is 7 - 9 psi the irony is almost no one has a gauge to accurately check the psi rating on a basketball while inflating it because most pumps aren’t equipped with a gauge and ones that are rarely give an accurate reading.
How to measure pressure how to measure flow by gjmatthews ©airflow developments limited but also an additional dynamic pressure equal to the velocity pressure in incompressible flow, due to the corrections for atmospheric pressure, air temperature, and duct pressure to. Flight begins with air in motion its wings cause changes in the speed and pressure of the air moving past them these changes result in the upward force called lift to understand lift, you first have to understand how air (a gas) behaves under certain conditions and dynamic pressure a: pressure is the continuous physical force. The understanding of air flow through and within buildings has assumed that wind forces, thermal effects (stack action), and air movement associated with mechanical cooling, heating and exhaust and other ventilation systems are the dominant factors relating to air pressure relationships and air pressure related building performance.
Dynamic pressure is a function of both air velocity and density: dynamic pressure = (density) (velocity) 2 / 2 the static and dynamic pressures are mutually convertible the magnitude of each is dependent on the local duct cross section, which determines the flow velocity. In the case of air pressure, air is pulled downward by the force of earth's gravitation, and air along the surface has greater pressure due to the weight (a function of gravity) of the air above it at great heights above earth's surface, however, the gravitational force is diminished, and, thus, the air pressure is much smaller. The dynamics of basketball bouncing how air pressure and temperature effect basketball rebound introduction hi the effect of air pressure obasketball authorstream presentation this project explores the interaction between air pressure and playing surface in determininbasketball ues bounce.
