The air has a dry ball temperature of 32 °C and a wet bulb temperature of 24 °C is heated in a heater so that the temperature of the dry ball increases to 90 °C. The air is then passed through the corn kernels pile to dry. air that comes out of the pile of corn kernels to dry. The air that exits the corn kernels is at a dry bulb temperature of 60 °C. then this air is passed to the dehumidifier to reduce its RH to 10 %.

Hypergolic propellants are fuels and oxidizers which ignite spontaneously on contact with each other.requiring no ignition source, hypergolics are ideal for spacecraft maneuvering systems as they provide an easy start and restart capability. Also, hypergolics do not pose the storage problems of cryogenic propellants (e.g., liquid oxygen and hydrogen) as they remain liquid at normal temperatures. This technology was used on the Apollo 11 Mission 40+ years ago. As part of the testing for a new thruster design, amounts of unsymmetrical dimethyl hydrazine, or UDMH [(CH3)2N-NH2; MW=60.1 g/mol] were reacted with dinitrogen tetroxide [N2O4; MW=92.1 g/mol]. The balanced equation for this reaction is shown below: (CH3)2NNH2(l) + 2 N2O4(g) → 3 N2(g) + 4 H2O(g) + 2 CO2(g) For one test, 721.2 grams of UDMH was completely consumed. How much dinitrogen tetroxide [in grams] was needed?
A mixture of gaseous reactants is put into a cylinder, where a chemical reaction turns them into gaseous products. The 1 atm pressure cylinder has a piston that moves in or out, as necessary, to keep a constant pressure on the mixture of 1 atm. The cylinder is also submerged in a large insulated water bath. (See sketch at right.) piston cylinder From previous experiments, this chemical reaction is known to release 297. kJ of energy. water bath gases The position of the piston is monitored, and it is determined from this data that the system does 111. kJ of work on the piston during the reaction.
