Generally‚ the automotive engine uses four strokes to convert chemical energy to mechanical energy through combustion of gasoline or similar hydrocarbon fuel. The heat produced is converted into mechanical

Lubricant A lubricant is a substance introduced to reduce friction between moving surfaces. It may also have the function of transporting foreign particles. The property of reducing friction is known as lubricity. Lubricant is a material that reduces the friction arising due to the sliding / gliding / rolling / moving of two different components in a machinery. Friction is an undesirable process that results in (i) wear and tear of the surfaces of the moving parts (ii) loss of enormous energy as

Physics Formulas: Mechanics Mechanics is the oldest branch of physics. Mechanics deals with all kinds and complexities of motion. It includes various techniques‚ which can simplify the solution of a mechanical problem. Here are some of the often required physics formulas falling in mechanics domain. Motion in One Dimension The physics formulas for motion in one dimension (Also called Kinematical equations of motion) are as follows. (Here ’u’ is initial velocity‚ ’v’ is final velocity‚ ’a’ is

Purpose The purpose of the experiment is providing an opportunity to students of experience to familiarize with some key aspects of fluid flow in pipe‚ notably friction losses and verify theory. In this experiment‚ required equipment are a water tank‚ piezometric tubes‚ pump‚ a stop watch‚ empty bucket and a digital weight scale. By operating the pump to keep the water is full in the water tank‚ and measuring the

essential to perform this experiment to understand the function of surfactant in the respiratory system. Base on this information‚ it can be hypothesis that when dish washer is added to the food coloring and the milk‚ the food coloring will reduce the friction between milk and dish washer. Diana Correa The importance of surfactant in the respiratory system In order for a new born baby to breathe‚ they need for their lungs to be able to expand. Surfactant help the expansions of the lungs by reducing
