Entry is free throughout the championships, which started on Saturday and run until Sunday, 5 October.
On announcing the choice of venue, Paul Fitzgerald, head of WPA, said that it would be the largest international Para sport event to take place in India, and represented a “massive opportunity to grow our sport, our fanbase, and to impact society’s perception of persons with disabilities in the world’s most populous nation”.
Cockroft, who will be taking part in three further events in what is her eighth World Championships, said she hoped word of mouth would see crowds grow.
“I just hope that the message is going out to the people of India that this event is happening,” she added.
“I want it to change attitudes, I want it to change mindsets around disability.
“We had a Commonwealth Games here, we know it is possible to fill the stands, so hopefully as the week goes on the word will get out and people will want to come and flood the stands and we will have a bit more support come to later events.”
GB’s Fabienne Andre finished third in the women’s T34 400m, behind team-mates Cockroft and Adenegan, but no bronze medal was awarded because there were only four athletes in the field.
The event had not featured in the past three World Championships, meaning Cockroft retained the title she last won in London in 2017.
Earlier, GB’s Thomas Young claimed bronze in the men’s T38 100m, finishing behind American Jaydin Blackwell, who won in a championship record time of 10.70, and his US team-mate Ryan Medrano.
