Two very large tanks, maintained at 323 k and 1 atm total system pressure, are connected by 0.1 m diameter circular duct, which is 5 min length. tank no. 1 contains a uniform gas mixture of 60 mol% acetone and 40 mol % air, whereas tank no. 2 contains a uniform gas mixture of 10 mol% acetone and 90 mol% air. determine the initial rate of acetone transfer between the two tanks. list the reason(s) why this process is considered "pseudo steady state"

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

Select any two (2) areas of applications of chain-drive. (clo4) a)-permanent lubrication necessary b)-hydraulic forklift truck operation c)-rigging and heavy moving materials d)-relatively high maintenance costs e)-costlier than belt drives

Acertain flow of air (at stp) has a velocity distribution given by v i (in ft/s). if this flow is going through a 4 ft square area in the yz-plane (centered at the origin), what is the mass flow rate (in lbm/s)?
