A = cross-sectional area of the opening (ft2). g = acceleration of gravity (32.2 ft/s2). h = height of water above the centerline of the flow (ft). The coefficient of discharge Cd is typically taken as 0.6, which means only 60% of the flow rate that would be expected from applyin...
Introduction So far, we have looked at cases where the rate of change is constant. For instance, we have considered a situation where when an equal amount of water is poured into a cylindrical beaker, the increases in height, after every instance, is the same. However, most situations in ...

What is the vertical component of acceleration? Does amplitude change with distance? How do you find the rate at which work is done? What is the equation of a velocity time graph when the velocity is constant at 0.17m/s? SI unit of rate of change in momentum? What is the change in ...
This could lead to a period of heavy discounting and an acceleration in the spot market erosion on the route. Elsewhere, on the transpacific, demand remains quite robust and carriers are having more success in holding onto their direct and indirect Red Sea crisis gains. For instance, the FBX...
Still, the 3-month-on-3-month (3m/3m) CPI measure has firmed recently and may indicate the disinflation path is bumpier than previously thought. The seasonally-adjusted 3m/3m measure shows an acceleration that is not reflected in the year-on-year measure. ...
When we observe any object which increases or decreases its speed with changing time, we call it non-uniform motion. Sir Isaac Newton proposed three equations of motion for non-uniform motion, which have a constant acceleration as written below. ...
The interesting thing to notice with this equation is actually the absence of certain variables like mass of the pendulum. This will be expanded on further, but it is good to remember that the period of a pendulum relies only on the length of the string and the gravitational acceleration (ex...
voltage proportional to the magnitude of acceleration and corresponding in polarity to the direction of the movement of the sensing element. Acceleration Sensor These sensors are called accelerometers and, as their name implies, measure acceleration, either linear or angular. Some measure the ...
g is the gravitational acceleration; Q is the flow rate; Hg is the gross head without deducting head losses; Hn is the net head after deducting head losses from the gross head; and η is the efficiency of the turbine and electrical generator. The availability of the designed flow rate thro...
