The four Bt brinjal varieties yielded on average 19.6 percent more than non-Bt varieties and earned growers 21.7 percent higher revenue. 83.1% of Bt brinjal growers were satisfied with the yields obtained and 80.6% were satisfied with the quality of fruit, compared to just 58.7% of non-Bt brinjal growers who were pleased with their yields.

A building's HVAC (heating, ventilating, and air conditioning) system can make use of an air-side economizer to save energy in buildings by using cool outside air as a means of cooling the indoor space. When the temperature of the outside air is less than the temperature of the recirculated air, conditioning with the outside air is more energy ...
H 1, H 2 are the total heat content of unit mass of vapors, respectively upstream and downstream the compressor. In SI units, these are respectively measured in kJ , kg and kJ/kg. The actual energy input will be greater than the theoretical value and will depend on the efficiency of the system, which is usually between 30% and 60%.
Air compressor supplies air into a nail gun.. An air compressor is a machine that takes ambient air from the surroundings and discharges it at a higher pressure. It is an application of a gas compressor and a pneumatic device that converts mechanical power (from an electric motor, diesel or gasoline engine, etc.) into potential energy stored in compressed air, which has many uses.
The compressed air rises to the top of the separation chamber (wind box). The separation chamber has a compressed-air takeoff pipe, and the compressed air can be used as a power source. The energy of the falling water creates a partial vacuum inside the pipe that is compensated by the air from the outside atmosphere provided through inlet.

The goal of having two heat exchangers is that the cold outgoing air cools down the hot incoming air and reduces the size of compressor required. At the same time the increase in the temperature of outgoing air prevents re-condensation. Some manufacturers produce "cycling dryers". These store a cold mass that cools the air when the compressor ...
Many refrigeration systems have the expansion valve set up inside the room being cooled, consequently generating productive refrigeration if absorbing heat from the room, to produce this kind of flash-gas between the expansion and the evaporator. Besides, the expansion valve deregulates its operation if the fluid arriving to it is boiling.
