A turbine blade made of a metal alloy (k = 17 W/m-K) has a
length of 5.3 cm, a perimeter of 11 cm, and a cross-sectional
area of 5.13 cm². The turbine blade is exposed to hot gas
from the combustion chamber at 1133°C with a convection
heat transfer coefficient of 538 W/m²K. The base of the
turbine blade maintains a constant temperature of 450°C
and the tip is adiabatic.
NOTE: This is a multi-part question. Once an answer is

Example 5.5 The turbine rotor of a ship has a mass of 30 tons, a radius of gyration
of 600 mm and rotates at 2400 rpm in a clockwise direction when viewed from aft. The
ship pitches through a total angle of 15, 7.5" above and 7.5° below the horizontal, the
motion being simple harmonic and having a period of 12 sec. Determine the maximum
gyroscopic couple on the holding down bolts of the turbine and the direction of yaw as
the Dow rises.
