Water flows over a spillway and is directed upward as a free jet at an angle of 30o y with the horizontal at the exit from the s

pillway. The upstream depth is 20 ft and the upstream velocity is 1 .5 ft/sec. The spillway width is 100 ft coming out of the paper (a) Find the magnitude of the velocity in the free jet at point 2. Neglect friction loss. (b) Determine the magnitude of the horizontal and /2.7) 7*r) by the water on the spillway.

Answer:

To calculate or compute the magnitude of the velocity at whichever point in time, you’ll need to multiply the constant acceleration pace times the amount of time difference and then adding the result to the initial velocity

While To calculate or compute the horizontal component, the magnitude of the vector will just be multiplied by the cosine angle referenced to the horizontal

what advantage might there be to having the encoder located on the motor side of the gearhead instead of at the output shaft of
UkoKoshka [18]

Answer:

The definition is defined in the clarification segment following the table, as per the particular circumstance.

Explanation:

  • In something like a closed-loop device, shaft encoders were being used, the output of which could be influenced either by encoder location. Most motors have been used for gearbox speed reduction (RPM). Assume there's also a gearbox reduction of 30:1 as well as the motor is already spinning at a higher 3000 rpm, then the outcome feature shaft speed would be 100 rpm.
  • This suggests that every other output shaft turning correlates to 30 input shaft flips, and even if the encoder contains 40 holes through its diameter, instead every output shaft revolution contributes to 40\times 30=1200 pulses. That implies an accuracy of 0.3 degrees of rotation of the final output shaft (\frac{360 \ degree}{1200} =0.3).  

Accuracy as well as reliability are thus given by positioning the encoder on the engine side instead of on the outcome shaft including its gear head.

Suppose a steam locomotive is rated at 7500 horsepower. If its efficiency is 6%, how much wood must be burned in a 3-hour trip?
Sati [7]

Answer:

50,625kg of wood

Explanation:

Power input = power output ÷ efficiency

Power output = 7500 horsepower = 7500×750W = 5625000W, efficiency = 6% = 0.06

Power input = 5625000/0.06 = 93750000W

Energy input = power input × time

time = 3hour = 3×3600 = 10800sec

Energy input = 93750000 × 10800 = 1.0125×10^12J

Mass = Energy ÷ Energy density = (1.0125×10^12J) ÷ (20×10^6J/kg) = 50,625kg of wood

Around the 1760s what allowed for more supplies to be moved around?
Licemer1 [7]

Around the 1760s the factor that allowed for more supplies to be moved around<u>-A free trade agreement</u>

<u />

Explanation:

A free trade agreement is a contract between two or more countries  to reduce the export and import  barriers . As per the  free trade agreement the  goods and services of a nation can be  bought and sold across international borders of other countries  and the  restriction imposed by the government (Like  tariffs, quotas, subsidies ) is restricted /limited in order to encourage free trade.

<u>The canton system of china is an example </u>

So the statement that Around the 1760s the factor that allowed for more supplies to be moved around<u>-A free trade agreement</u>
