When immersed in a uniform stream, a thick elliptical plane cylinder creates a broad downstream wake, as idealized in fig. p3.72. the pressure at the upstream and downstream sections are approximately equal, and the fluid is water at 208c. ifu054m/sandl580cm, estimatethedrag 1 cm force on the cylinder per unit width into the paper. also compute the dimensionless drag coefficient cd 5 2f/(rhou20bl).

Explain the difference laminar and turbulent flow. explain it with the shear stress and the velocity profiles.

When at a point two solid phase changes to one solid phase on cooling then it is known as a) eutectoid point b) eutectic point c) peritectic point d) peritectoid point

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
