The difference between isothermal compressibility and adiabatic compressibility for an ideal gas is________?
When does the heat generated by fluid friction becomes appreciable compared to the heat transferred between the fluids?
Interstage coolers are provided in a multistage compressor to________?
Functional depreciation of an equipment is the measure of decrease in its value due to its ________?
Second order consecutive irreversible reaction as shown in the bellow figure, were carried out in a constant volume isothermal batch reactor with different initial feed compositions. Reactor temperature was same in all the cases. In experiments where the ratio of concentration of B to that of A in the initial feed was less than 0.5, the concentration of B increased first, reached a maximum and then declined with time. However, for all experiments where this concentration ratio was 0.5 or above, concentration of B decreased monotonically with time right from the beginning. What is the ratio of the two rate constants (k1/k2)?
Compressibility co-efficient for an absolutely compressible cake is________?
