An investigation of a die-casting process resulted in the accompanying data on x1 = furnace temperature, x2 = die close time, and y = temperature difference on the die surface†. x1 1250 1300 1350 1250 1300 1250 1300 1350 1350 x2 6 7 6 7 6 8 8 7 8 y 80 95 101 85 92 87 96 106 108 The software output from fitting the multiple regression model with predictors x1 and x2 is given here.

Calculate the bore of a cylinder that has a stroke of 18 inches and an extension time of 6 seconds at a flow rate of 4 gal/min.

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
