Answer:
Width w = 4m
Glow depth = y1 = 20m
Outlet discharge = 40m
V1= velocity of flow = 40/20*4 = 1/2 = 0.5m/s
Froud number = v1/√gy1
= 0.5/√9.81x20 = 0.0356
1. Y2/20 = 1/2[-1+√1+8*(0.0356)²]
Y2 = 0.05
2. Energy loss in the jump = (20-0.05)²/4x20x0.05
= 1985m

Answer:
a)True
Explanation:
While machining of ductile material and high feed and low cutting speed welding action take place between tool material and chip material this welding action is called built up edge. Built up edge action takes place due to high temperature.
To decrease the built up edge action
1. Increase the rake angle.
2. Increase the cutting speed
3. Decrease the feed rate
4. Use cutting fluid
