Respuesta :
The the diameter of the shaft is to be in order to transmit 60 hp at 150 rpm 1.88 inch.
Explain the term horsepower?
- Power is measured in hp, which is the standard abbreviation for horsepower.
- The rate of job completion can be used to describe power in this context.
- Most frequently, the term "horsepower" is used to describe an engine or motor's output.
We must first obtain the formula for calculating horsepower.
The phrase to use is as follows:
hp = k × v × d³ ......eq(1)
Where:
- hp is horsepower
- v is speed (in rpm)
- d is diameter
- k is constant of horsepower.
Since k is a constant, it will always have the same value when the shaft is transferring 60 horsepower at 150 rpm.
Therefore, using the first set of information, we can determine the value of k and subsequently the diameter.
When we solve for k in (1), we get:
k = hp / (v × d³)
Put the values;
k = 45 / (100 × 3³)
k = 0.02
Put the value of k and solve for diameter.
d = ∛hp / (k × v)
d = ∛60 / (150 × 0.06)
d = 1.88 inch
Thus, the the diameter of the shaft is to be in order to transmit 60 hp at 150 rpm 1.88 inch.
