Experiments have shown that, for airflow at = 35°c and = 100 m/s, the rate of heat transfer ∞1 from a turbine blade of characteristic length l1 = 0.15 m and surface temperature = 300°c is =1500 w. what would be the heat transfer rate from a second turbine blade of characteristic length l2 = 0.3 m operating at = 400°c in airflow of = 35°c and v2 = 50 m/s? the surface area of the ∞ blade may be assumed to be directly proportional to its characteristic length.

According to newton's second law, when the same force is applied to two objects of different masses, a the object with greater mass will experience a great acceleration, and the object with less mass will experience an even greater acceleration, b. the object with greater mass will experience a smaller acceleration, and the object with less mass will experience a greater acceleration, c. the object with greater mass will experience a greater acceleration, and the object with less mass will experience a smaller acceleration, d. the object with greater mass will experience a small acceleration, and the object with less mass will experience an even smaller acceleration.

The average density of the planet uranus is 1.27 103 kg/m3. the ratio of the mass of neptune to that of uranus is 1.19. the ratio of the radius of neptune to that of uranus is 0.969. find the average density of neptune.
