aNow the total number of trays in the prefractionator and main column, location of feed and side draw and the interlinking trays in the main column are found from the result of the stage-to-stage com- putation. Because the structural design of this study is based on the ideal distillation...
Assertion (A): If the roots of (a^(2)+b^(2))x^(2)-2b(a+c)x+ (b^(2)+c^(2))=0 are real and equal then a, b, c are in G.P. Reason (R): If the sum of two non-n
The meaning of ROOT is the usually underground part of a seed plant body that originates usually from the hypocotyl, functions as an organ of absorption, aeration, and food storage or as a means of anchorage and support, and differs from a stem especiall
