Atrue centrifugal casting operation is to be performed in a horizontal configuration to make cast iron pipe sections. the sections will have a length = 42.0 in, outside diameter = 8.0 in, and a wall thickness = .50 in. if the rotational speed of the pipe = 500 rev/min. will the operation be successful? hint: calculate gf using outside diameter of the pipe.

Assuming compressible flow of air and that the measurements are done at flagstaff a pitot static tube that gives the difference of total and static pressure measures 0.35 m of mercury. what is the velocity of air? assume the temperature to be 300k. (submit your excel or matlab calculation sheet)

Ahot wire operates at a temperature of 200°c while the air temperature is 20°c. the hot wire element is a tungsten wire of 5 um diameter and 2 mm in length. plot using excel current, heat transfer and heat generated by the wire for air velocity varying from 1-10 m/s in steps of lm/s? matlab the sensor voltage output, resistance, or assume nu 0.989 re033pr13 take air properties at tr (200°c20°c)/2 = 110°c properties of tungsten: c 0.13 kj/kg.k 3 p 19250 kg/m k (thermal conductivity) = 174 w/m.k

What is the main objective of using reheat rankine cycle?
