Aviscometer may be created by using a pair of closely fitting concentric cylinders and filling the gap between the cylinder with the fluid whose viscosity will be measured. assuming that the velocity profile in the gap is linear, calculate coefficient of viscosity if inner diameter is 75mm, outer diameter is 75.04mm, torque is 0.021 n/m and w is 100 rpm.

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

When using the ohmmeter function of a digital multimeter, the leads are placed in what position relative to the component being tested? a. parallel b. control c. series d. line

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
