Final answer:
A porter governor is a type of governor used in engines to control speed. The maximum speed, range of speed, sleeve lift, governor effort, power of the governor, and governor sensitivity can be determined by using various equations.
Step-by-step explanation:
A porter governor is a type of governor used in engines to control the speed. In this case, the governor has equal links, each 250 mm long, and each ball has a mass of 4 kg. The central load, which is at the center of the governor, has a mass of 15 kg. The governor begins to lift when the ball radius is 150 mm and has a maximum speed at a radius of 200 mm.
The maximum speed can be determined by using the equation for velocity of a point on the governor, which is given by v = ω*r, where ω is the angular velocity and r is the radius. The range of speed can be determined by subtracting the minimum speed (when the balls are at the lower position) from the maximum speed. The sleeve lift is the difference in height of the governor when the balls are at the minimum and maximum radii. The governor effort can be found using the equation Fc = m*a, where Fc is the centrifugal force, m is the mass, and a is the angular acceleration. The power of the governor can be found using the equation P = Fc*v, where P is power.
The governor sensitivity can be determined by dividing the range of speed by the sleeve lift.
