Smeaton also devised a formula that was used by the Wright brothers during their legendary quest to fly. The formula uses a coefficient, called the Smeaton’s coefficient used to calculate drag due to air. He improved the design of the Diving Bell ( developed by Edmond Halley ) so that it could be used underwater. He achieved this by using a force pump that maintained the pressure & fresh air inside the diving bell, even after it was submerged. 

Awards

John Smeaton was made a fellow of the Royal Society of London for his work in constructing precision instruments. He also won the Copley award for his research work on Windmills and watermills

Personal Life
