Answer: c) 450 kPa
Explanation:
Boyle's Law: This law states that pressure is inversely proportional to the volume of the gas at constant temperature and number of moles.
(At constant temperature and number of moles)
where,
= initial pressure of gas = 150 kPa
= final pressure of gas = ?
= initial volume of gas = v L
= final volume of gas =
Therefore, the new pressure of the gas will be 450 kPa.
Answer:
The torque torque produced on the turbine from the wind is approximately 955 kN·m
Explanation:
The number of revolution per minute of the turbine = 20 rev/min
The power output of the turbine = 2.0 MW
The power transmitted to a shaft equation is given as follows;
Where;
P = The power transmitted to a turbine shaft = 2.0 MW
N = The number or revolutions per minute = 20 rev/min
T = The torque produced on the turbine by the wind
Therefore;
The torque torque produced on the turbine from the wind = 3/π MN·m ≈ 0.955 MN·m = 955 kN·m.
