Q2. Grades of concrete
Ans. 
Grades of concrete refer to the strength of the concrete mix design.
• Grades of concrete are denoted by M10, M15, M20, etc. where M stands for mix and the number represents the compressive strength in N/mm^2.

• Higher grade concrete has higher compressive strength and is used for structural purposes.

• Common grades include M25, M30, M35, and M40 for heavy-duty structures like bridges and high-rise buildings.

Q1. Pressure in fire hydrant pipe
Ans. 
Pressure in fire hydrant pipe is determined by factors like water flow rate, pipe diameter, and elevation difference.
• Pressure in fire hydrant pipe is directly related to the flow rate of water through the pipe.

• The diameter of the pipe also affects the pressure, with larger diameter pipes resulting in lower pressure loss.

• Elevation difference between the hydrant and the point of discharge can impact the pressure in the p...read more
