Water at a pressure of 3 bars enters a short horizontal convergent channel at 3.5 m/s. The upstream and downstream diameters of
the channel are 50 mm and 30 mm respectively. Determine the downstream pressure if energy losses are neglected.
1 answer:
Answer:
The pressure reduces to 2.588 bars.
Explanation:
According to Bernoulli's theorem for ideal flow we have

Since the losses are neglected thus applying this theorm between upper and lower porion we have

Now by continuity equation we have

Applying the values in the Bernoulli's equation we get
