A low-speed compressor has stator vanes that are to have an inlet flow angle of 45 and anexit flow angle of 25.
a. Calculate the pitchchord ratio of the stators assuming a Lieblein diffusion factor of 0.45.Using Lieblein's diffusion factor reaching 0.6 as a criterion, and assuming that the exitflow angle remains constant, determine the incidence that corresponds to the blade stalling.
b. Use Carter's deviation correlation to estimate the required metal exit angle given that aparabolic arc camber line is employed with maximum camber at 40% chord. (Note thatsome iteration is needed.)

heat transfer to a 1.5kg block of ice at -10 degrees celsius melts it to a liquid at 10 degrees celsius in a kitchen.
You want to know if you should replace the existing machines, which has a Cpk of 1.0. You decide to determine the Cpk for the new machines and make a decision on that basis.
A freely (zero friction) rotating cylinder (mounted on a vertical axis) is placed on a model boat instead of a sail. The Magnus force that is created is used to power the boat. A fan is mounted on the boat to provide airflow over the cylinder.
