1. What happens if the vanes of a pump are forward curved? 2. Why the entropy of a system always increase? 3. What is the chemical difference between SS321 & SS347? 4. Draw the pressure distribution diagram of journal bearing lubrication.

Question

Accepted Answer

1. Forward curved vanes of a pump increase efficiency but are more prone to wear. 2. Entropy always increases due to the second law of thermodynamics. 3. SS321 has higher carbon content than SS347. 4. Pressure distribution in journal bearing lubrication is highest at the center.

Forward curved vanes in a pump help in reducing noise and vibration while increasing efficiency.
Entropy always increases in a system due to the tendency of energy to disperse and reach equilibrium.
SS321 contains more carbon and is more susceptible to sensitization compared to SS347.
In journal bearing lubrication, pressure is highest at the center and decreases towards the edges.
