Two insulated tanks, labelled a and b, are connected by a valve that is initially closed. tank a contains air at 100 kpa and 350 k and has a volume of 0.75 m3. tank b contains air at 800 kpa and 1000 k and has a volume of 0.5 m3. find the final temperature and pressure of the air after the valve is opened and the contents of the two tanks have mixed.

On a average work day more than work place firs are reorted

An electrical motor raises a 50kg load at a construct velencity .calculate the power of the motor, if it takes 40sec to raise the load through a height of 24m(take g =9.8n/g)

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
