5.You are designing the fit for two bearings. For each case, specify the maximum and minimum hole and shaft diameter:a.A journal
bearing and bushing with basic size is 1.25 in that requires a close running fit.b.A ball bearing assembly with basic size 35 mm that requires a locational interference fit.

Answer:
manning's coefficient is 0.0357
Explanation:
Given:
Velocity of flow, v = 12 m/s
Width of the channel, b = 6 m
Depth of the channel, d = 2 m
bed slope, s = 0.001
mean velocity of flow, V = 1 m/s
now, the velocity is given as:
where,
n is the manning's coefficient
R is hydraulic mean depth
R = (Area of the channel) / (wetted Perimeter of the channel)
now,
R = (2 × 6) / ((2 × 2) + 6)
or
R = 12 / 10 = 1.2 m
now, on substituting the values in the equation for velocity, we get
or
or
n = 0.0357
hence, the value of manning's coefficient is 0.0357
