Mention the most important mechanical properties for specifying materials used in chemical processes/plant.
List the typical utilities needed in Utility Flow Diagrams.
Two liquid storage tanks are shown in Figure Q2. For System I, the valve acts with a resistance R = 580 s m-2, so that the relation between the flow (F)and liquid level in the tank (h) is given by F = hlR. For System II, a pump is used instead of the valve, meaning that variations in liquid level do not affect the exit flow rate. The diameter of each tank is the same, D = 1.1 m. For each system determine the following information and show all your workings: (a) Process gain (Kp) and time constant (7). (b) New steady-state liquid levels in both System I and System II, if the inlet flow rate suddenly changes from 3.0x10-3 m³ s-1 to4.5x10-3 m3 s-1. The initial steady-state level in both systems is 1.8 m. (c) If each tank is 2.4 m tall, which tank overflows first? Calculate when this will happen.
Explain the working principle of Turbine meters with neat sketch.
Discuss the different modes of heat exchange in a typical fired heater shown below.
Differentiate single effect and multiple effect Mechanical vapor recompression (MVR).
A can of hair spray is used until it is empty except for the propellant,isobutene gas. a) On the can is the warning "store only at temperature below 120'F(48.8'C). Do not incinerate. Why? b) The gas in the can is initially at 24'C and 360 kPa and the can has the volume of 350mL. If the can is left in a car that reaches 50'C on a hot day,what is the new pressure in the can?
A control system has the following transfer functions: Gc = Kc, GvGp = 1/(s+1) (0.5s+1)2
