The hydraulic cylinder operates the toggle, which closes the vertical gate against the pressure of fresh water on the opposite side. the gate is rectangular with a horizontal width of 2 m perpendicular to the paper. for a depth h=3 mof water, calculate the required oil pressure, p, which acts on the 200mmdiameter piston of the hydraulic cylinder

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
