How can we increase the efficiency of a diesel engine?
How can we increase the efficiency of a diesel engine? Run the engine fuel-lean, that is, use excess air. It is well known that fuel-lean running improves the efficiency. Higher compression ratio. We need new cycles put into practical use. Run the engine at optimum conditions, meaning low friction (modest engine speed) and low pumping […]
Why is bitumen used in road construction?
Why is bitumen used in road construction? Asphalt road surfaces are also considered a sustainable option for road paving material where bitumen is used as binder as this material can be recycled. The bitumen, produced by the refineries, plays an important role in road durability which is also important for sustainability. What is the purpose […]
What happens to the potential energy of a ball that is dropped from a height?
What happens to the potential energy of a ball that is dropped from a height? When a tennis ball is dropped from 2 m, it possesses a certain amount of gravitational potential energy because of its mass and its height above the ground. As the ball falls, that energy is converted to kinetic energy. How […]

How does a cooling tower system work?
How does a cooling tower system work? Cooling tower systems work by using water to extract waste heat from a system and ejecting it into the atmosphere primarily through evaporation. The three key components of a cooling system are the cooling tower, recirculating pump, and heat exchanger. Water first passes through a heat exchanger where […]
