He following waveforms are measured through a particular device: LaTeX: v(t)= 20\cos(100t+50^{\circ})Vv ( t ) = 20 cos ⁡ ( 100 t + 50 ∘ ) V LaTeX: i(t)=15\cos(100t-5^\circ)Ai ( t ) = 15 cos ⁡ ( 100 t − 5 ∘ ) A What is the power angle? Submit your answer in degrees, while omitting the unit.

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
