3. Two boxes contain 4 balls each numbered from 1 to 4. An experiment consists in selecting randomly one ball from each box. Given that the sum of the 2 numbers coming up is greater than 6, the probability that the sum of the numbers is even is equal to

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

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

The maximum shear stress and maximum flexural stress occur at the same location along a beam subjected to a non-uniform bending load. a)-trune b)- false
