What does insufficient demand load calculation lead to in a gas distribution system?

1. Reduction of installation time

2. Improper sizing of pipes

3. Increased efficiency of appliances

4. Lower operational costs

The correct answer is: Improper sizing of pipes

Insufficient demand load calculation leads to improper sizing of pipes in a gas distribution system because it results in an inaccurate assessment of the amount of gas needed by the appliances. When the demand load is underestimated, the pipes may be sized too small, limiting the gas supply to the appliances and potentially causing underperformance. Correct pipe sizing is crucial in ensuring that the gas distribution system can deliver the right amount of fuel to meet the peak demand. If the pipes are too small due to an insufficient load calculation, it can lead to issues such as inadequate gas pressure during times of high demand, affecting appliance operation and efficiency. Thus, proper demand load calculations are essential for the reliable and efficient functioning of the gas distribution system.
