Acompound drop consists of an oil droplet of diameter 0.5mm inside a water droplet of diameter 2mm at atmospheric pressure and room temperature. if the interfacial tension between water and oil is 30mn/m, what is the pressure inside the oil drop?

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

Determine whether or not it is possible to compress air adiabatically from k to 140 kpa and 400 k. what is the entropy change during this process?

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
