- Q1. How is flow affected with change in velocity in a venturimeter.
- Ans.
Velocity change affects flow in a venturimeter.
As velocity increases, pressure decreases and vice versa.
Flow rate is directly proportional to the square root of pressure difference.
Venturimeter is used to measure flow rate in pipes.
Flow rate can be calculated using Bernoulli's equation.
- Q2. Which is better cstr/pfr for zero order reaction.
- Ans.
PFR is better for zero order reaction as it maintains constant concentration throughout the reactor.
PFR maintains constant concentration throughout the reactor
CSTR may result in concentration gradients
PFR is more efficient for zero order reactions
CSTR may be more suitable for reactions with changing rate constants
