Assertion: turbine's speed | /r/HasProperty | equal
Facets:
value: in each of the three regions
type: LOCATION
value: to the initial jet velocity
type: OTHER
Source sentences:
text: When the speed of the runner is equal to the initial jet velocity, the torque is zero (i.e. when u = V i , then T = 0).
text: So the density times the area and speed should be equal in each of the three regions: before, while going through the turbine and afterward.
