31. On 8 bolts, the fatigue damaged area exceeded 90 % of the total cross-sectional area . 32. An additional rating curve is constructed that relates stage of the stream to cross-sectional area . 33. As cross-sectional area decreases in the valve, velocity increases and pressure drops as a result. 34. The resistance of a given material increases with length, but decreases with increasing cross-sectional area . 35. The universal transformer equation indicates a minimum cross-sectional area for the core to avoid saturation. 36. The flow is calculated by multiplying the mean velocity by the cross-sectional area of the vessel. 37. In conventional deformation processes like drawing, strain is introduced by reduction in the cross sectional area . 38. The resistance of a conductor at DC ( 0 Hz ) depends on its cross-sectional area . 39. Average velocities and the cross-sectional area of the stream are measured for a given stream level. 40. The larger the total cross-sectional area , the lower the mean velocity as well as the pressure.
