1. A component for a turbine engine, comprising:
a wall having a first wall surface and a second wall surface; and
a cooling hole comprising a connecting passage extending between an inlet at the first wall surface and an outlet located at the second wall surface, wherein the connecting passage includes:
a metering section extending from the inlet toward the outlet and defining a centerline, and
a diffusing section at the outlet defining first and second side walls, a first junction between the first side wall and the metering section and a second junction between the second side wall the metering section, the first side wall extending between the first junction and the outlet, and the second side wall extending between the second junction and the outlet;
wherein a metering section distance is measured between the centerline and a metering section wall of the metering section;
wherein the metering section distance is measured in a first direction perpendicular to the centerline;
wherein a first distance is measured downstream of the first junction between the centerline and the first side wall, wherein the first distance is measured in a second direction perpendicular to the centerline, wherein the first distance is greater than the metering section distance and increases moving in a third direction from the first junction to the outlet;
wherein a second distance is measured downstream of the second junction between the centerline and a second side wall, wherein the second distance is measured in a fourth direction perpendicular to the centerline, where the second distance is greater than the metering section distance and increases moving in a downstream direction from the second junction to the outlet; and
wherein the first junction is offset from the second junction in the downstream direction along the centerline.
