An older Rolls Royce Ghost is traveling at 25 mph on a roadway with good, dry pavement.The car has a C D = 0.32, 35 ft 2 of frontal area, and weighs 5,445 lb. The wheelbase is 129.7 inand the center of gravity is 25 in above the pavement and 60 in behind the front axle. Thevehicle is traveling on pavement at sea level. The engine produces a hefty 620 ft-lb of torqueand is in a gear of the transmission that provides a gear reduction of 5 to 1 with a 22 in wheelradius and 95% drivetrain mechanical efficiency. If the limo driver needs to accelerate hard inthe Ghost to avoid an accident, what would the acceleration be since it is a rear-wheel drive car?
Explain, with the use of sketch diagrams, why the aerodynamic force on a blade has to be resolved twice to obtain the accelerating force on a wind turbine rotor.
At what speed would these fans operate to develop 130 mm water gage when the temperature is 316 deg C? The fans of a certain manufacturer are rated at 152 mm water gage pressure for 10 cubic meters of air per second at 21 deg C, 1200 rpm, and 69% static efficiency
