Impact Of a Jet Introduction: Over the years‚ engineers have found many ways to utilize the force that can be imparted by a jet of fluid on a surface diverting the flow. For example‚ the pelt on wheel has been used to make flour. Further more‚ the impulse turbine is still used in the first and sometimes in the second stages of steam turbine. Firemen make use of the kinetic energy stored in a jet to deliver water above the level in the nozzle to extinguish fires in high-rise buildings

edges the acoustic flow velocity amplitude is comparable to the main flow velocity. A two-dimensional potential flow model based on the vortex blob method‚ used to simulate the flow in the junction‚ describes accurately the flow visualization and laser Doppler data obtained in pipes with square cross-sections and with sharp edged junctions. The numerical simulation is used to calculate the acoustical power generated by the vortical flow at a given amplitude of the acoustic velocity field and Strouhal number

Title: How does a moving cart rolling down a slope? Objectives: Adapt the traditional vertical and horizontal axes to a coordinate system aligned with a slope. Determine the acceleration of a cart that rolling down from a frictionless track (our assumption) by calculating theoretically and measuring experimentally. Compare the experimental and expected values of acceleration. Show that the acceleration of a cart moving down a slope (from frictionless track) is dependent on the angle of the slope

Purpose: To find the initial velocity of a marble leaving a ramp using time‚ range‚ and background information learned in class. Equipment: The equipment used in this experiment was a toy track and ramp‚ a small marble‚ multiple Physics textbooks‚ meter sticks‚ bright-colored cardstock‚ masking tape‚ sidewalk chalk‚ plastic bag and a cloth. Procedure: Our experimental values include the height that the marble would travel‚ y= 88.1 cm‚ and our ramp angle‚ θ= 44.0°. These independent variables

of design will experience three phases of apparent weight: the lifting‚ falling and braking stages. At first‚ the rider will feel heavier as the carriage accelerates. Then‚ as the velocity is constant‚ the apparent weight will equal that of the real weight. Finally‚ as the ride slows at the top‚ the decreasing velocity will result in a lighter feel. During free fall‚ riders will feel weightless‚ before experiencing a dramatic increase in apparent weight during the braking stage. As the ride climbs
