Question
Chapter 24, Problem 1RQ
To determine
The necessity to have intake charge velocities of about 50 feet per second.
Expert Solution & Answer

Explanation of Solution
The velocity of the fuel at the intake must be high enough to overcome the airstream between the intake value and the throttle body. At speeds more than 300 feet per second, the separation of droplets from the charge will occur. In order to prevent the droplet separation, the intake charge velocity must be around 50 feet per second. Hence, it is necessary to have intake charge velocity of about 50 feet per second to prevent the droplet fallout.

Qu 3 Nickel (Ni) single crystal turbine blades burn less fuel at higher temperatures because blades are grown on [110] closed packed direction. Nickel (Ni) at 20°C is FCC, and has an atomic radius, R, of 0.125 nm. Draw a reduced-sphere unit cell for this crystal and draw and label the vector [I 10], starting from the origin (0, 0, 0).
a) Calculate the length of the vector [| 10] in nanometers. Express your answer in nanometers to one significant figure.
b) Calculate the linear density of Nickel in the [| 1 0] direction in [atom/nm]. Express your answer in atoms/nm to one significant figure.
