An operation being done in a way that intervening operation can be occurred, this operation is called a
Dispersion of a process in monitored in
In a 1-1 pass floating head type shell and tube heat exchanger, the tubes (od = 25 mm; id = 21 mm) are arranged in a square pitch. The tube pitch is 32 mm. The thermal conductivity of the shell side fluid is 0.19 W/m.K, and the Nusselt number is 200. The shell-side heat transfer coefficient (in W/m2. K), rounded off to the nearest integer, is
The characteristic equation for a system is s3 + 9s2 + 26s + 12(2 + Kc) = 0. Using the Routh test, the value of Kc that will keep the system on the verge of instability is
A thermometer initially at 100°C is dipped at t = 0 into an oil bath, maintained at 150°C. If the recorded temperature is 130°C after 1 minute, then the time constant of thermometer (in min) is
In the McCabe-Thiele diagram, if the x -coordinate of the point of intersection of the q -line and the vapor-liquid equilibrium curve is greater than the x -coordinate of the feed point, then the quality of the feed is
