Answer:
b)false
Explanation:
As we know that
Volume flow rate Q
Q = A x V
For constant volume flow rate,if velocity will increase then automatically area will decrease and vice versa.
Generally nozzle are used to increase the velocity and diffuser are used to decrease the exit velocity of flow.
So by increasing the cross sectional area of the restriction ,the velocity of the flow will decrease.
Answer:
Noise or sound is the energy produced by sounding object which can be felt by our hearing organs .
Explanation:
Noise is produced by vibration in a body.
Answer:
Rate of corrosion = 24.95 mpy
Rate of corrosion = 0.63 mm/yr
Explanation:
given data
steel sheet area = 150 in²
weight loss = 485 g
density of steel = 7.9 g/cm³
time taken = 1 year
to find out
rate of corrosion in (a) mpy and (b) mm/yr
solution
we get here the rate of corrosion that is express as
rate of corrosion = (k × W) ÷ (D × A × T) ..................1
here k is constant and w is total weight lost and t is time taken for loss and A is surface area and D is density of steel
so put her value in equation 1 we get
Rate of corrosion = 
Rate of corrosion = 24.95 mpy
and
Rate of corrosion = 
Rate of corrosion = 0.63 mm/yr
