Answer:
The gauge pressure is 1511.11 psi.
Explanation:
Given that,
Flow rate = 94 ft³/min
Diameter d₁=3.3 inch
Diameter d₂ = 5.2 inch
Pressure P₁= 15 psi
We need to calculate the pressure on other side
Using Bernoulli equation
We know that,
Where, V = volume
v = velocity
A = area
Put the value of v into the formula
Put the value into the formula
We need to calculate the gauge pressure
Using formula of gauge pressure
Put the value into the formula
Hence, The gauge pressure is 1511.11 psi.
Answer:
When an object moves in a straight line at a steady speed, we can calculate its speed if we know how far it travels and how long it takes. This equation shows the relationship between speed, distance traveled and time taken: Speed is distance divided by the time taken.
Explanation:
Thats what goog.le said so if its wrong blame G O O G L E
Using s=1/2 a t ^2
25 = 1/2 x 0.5 x t^2
t = square root (25/0.25)
t = 10 seconds
Answer:
15 miles
Explanation:
Alicia's speed in the first part of the race is:
where is the length of the first part and the time taken to cover this part.
Alicia's speed in the second part of the race is:
where is the length of the second part and the time taken to cover this part.
The total length of the race is
And the total time taken by Alicia to complete the race is
We have in total 4 equations with 4 unknown quantities. From the first 2 equations we find:
And substituting into the second group of equations:
Calling A the first equation and B the second equation, if we compute (A-8B) we get:
And so
So Alicia runs for 1.25 hours at 12 mph (second part of the race). Therefore, the distance travelled during this part is:
Therefore the answer is 15 miles.
