A vacuum gauge is a pressure gauge used to measure pressures lower than the ambient atmospheric pressure, which is set as the zero point, in negative values (e.g.: −15 psig or −760 mmHg equals total vacuum).
Answer:
F= 5 N
V= 4 m/s
Explanation:
Given that fluid is Newtonian fluid .As we know that for Newtonian fluid the shear stress given as
We also know that
Force = shear stress x area of plate
Now by putting the values
Here velocity of fluid profile is linear.
τ= 2.5 Pa
So force = 2.5 x 2
F= 5 N
Now when fluid is replaced by another fluid but force is constant.The height of plate is also constant.
Lets take velocity of fluid is V in the new condition
So we can say that
Now by putting the value
50 x 0.4 = 5 x V
V= 4 m/s
A driver should have at least a <u>10 mph</u> speed advantage when overtaking (passing) another vehicle.
<h3>What is a speed limit?</h3>
A speed limit refers to the maximum amount of speed that is legally permitted or allowed in a specific area for safety. Thus, this limit must be abided and strictly adhered to by all road users such as drivers of a vehicle.
According to the highway traffic code and regulations, a driver should have at least a <u>10 mph</u> speed advantage when overtaking (passing) another vehicle.
