Answer with explanation:
As is the question the answer would be 19 hours, and the key to solving it is in the phrase in 15 more hours, basically what they are saying is that the small pipe takes 15 hours more than both the big and the small to fill the tank. Since both pipes working together can fill the tank in 4 hours we need to add 4 and 15 to solve the problem.
If the question is how many hours would it take to fill the tank using only the big pipe? Then we could solve t for the following equation:
Getting as a result: 5.06
Note that the equation is the result of taking the rate of the small pipe (what we solved before), plus the unknown rate of the big one equals the rate of both.
Answer:
(b) an equivalent AC current source in parallel with an equivalent reactance
Explanation:
The Norton AC equivalent circuit is composed of a Norton current service as the source, and it is in parallel to a Norton resistor, which can be valid for any type of load. Norton equivalent circuit is valid for a single frequency in AC circuits.
Answer:
What Is Normal Oil Pressure Temperature? Oil temperatures typically range from 200 degrees to 200 degrees Fahrenheit, depending on the weather. The oil pressure ranges from 100psi to 10-15psi depending on the weather at start up.
Explanation:
The answer & explanation for this question is given in the attachment below.
Answer:
Flow rate = 118.8 gpm, discharge pressure= 331.5 psig, shaft power = 26.3 hp and Efficiency = 87.5%.
Explanation:
Without mincing words, let us dive straight into the solution to the question above. So, the following parameters or data are given in the question above:
gpm = 80 gpm, shaft power = 8hp, and the pressure of 150 psig.
The flow rate =[ 80 × 1500] ÷ 100g = 118.9 gpm.
Hence, the discharge pressure = 150 × [ 1500/100]² = 331.5 psig.
Also, the required shaft power = 8 × [ 1500/100]³ = 26.3 hp.
The last part that is the efficiency can be calculated as given below:
Efficiency = [ 80 × 0.00223 × 144 × 150 ] ÷ [550 × 8 ] = 0.875 = 87.5%.
