How do you determine if there is a hydraulic jump?
How do you determine if there is a hydraulic jump? A hydraulic jump occurs when the upstream flow is supercritical (F>1). To have a jump, there must be a flow impediment downstream. The downstream impediment could be a weir, a bridge abutment, a dam, or simply channel friction. Water depth increases during a hydraulic jump […]

Is there a direct relationship between time in the air and the range?
Is there a direct relationship between time in the air and the range? There is no direct relationship between air time and range because when the initial angle changes, the initial velocity divides into x and y components. as x-velocity increase, the range increases up 5. What is the purpose of a motion graph? Describing […]
