Answer:
P = 0.14 hp
Explanation:
The power required by the ship is given as:
where,
P = Power = ?
m = mass to pump = (12 lb)(1 kg/2.20 lb) = 5.44 kg
g = acceleration due to gravity = 9.81 m/s²
h = height = 2 m
t = time = 1 s
Therefore,
Converting to horsepower (hp):
<u>P = 0.14 hp</u>
Answer:
The length of the resonating air column is 15 cm.
Explanation:
Given;
fundamental frequency of the air column, F₀ = 550 Hz
Assume speed of sound in air, v = 330 m/s
The wavelength of the air column is calculated as;
The length of the resonating air column is calculated as;
In fundamental mode for closed pipe;
Therefore, the length of the resonating air column is 15 cm.
