A class of students performed the heat transfer experiment shown in the picture. In the experiment, three plastic dishes were pa
rtially filled with equal amounts of dark soil, light soil, and water. Thermometers were placed in each dish, and the dishes were placed under a heating lamp. The substances were left under the heating lamp for ten minutes, and their temperatures were observed and recorded. After recording the temperatures of the substances as they were heating, the students turned the lamp off and recorded the temperatures of the substances as they cooled for ten minutes.

Answer:
The depth of the water at this point is 0.938 m.
Explanation:
Given that,
At one point
Wide= 16.0 m
Deep = 3.8 m
Water flow = 2.8 cm/s
At a second point downstream
Width of canal = 16.5 m
Water flow = 11.0 cm/s
We need to calculate the depth
Using Bernoulli theorem
Put the value into the formula
Hence, The depth of the water at this point is 0.938 m.
