If the bucket is being lowered at a constant downward velocity, then the net force acting on the bucket must be zero. Therefore, the tension in the rope (acting upwards) must exactly balance the weight of the bucket (acting downwards). Thus, the tension in the rope must be equal to the weight of the bucket.
