1. Objective

1) Learn about the continuity equation and the Bernoulli equation.
2) Measure the head loss at various diameter pipes and various fittings by measuring the pressure difference.

2. Result

Gravitational acceleration : 9.8m/s²
Temperature : 16℃
Density : 998.97kg/m³ (Table1)
Viscosity: 1.111cP (Table1)
Kinematic viscosity: viscosity/density = 1.112×10⁻⁶
Cross-section Area:
Flow rate(m³/s) : volume(m³) / time(s)
Velocity : Flow rate / Area
= diameter×velocity/kinematic viscosity

3. Discussion
1) Compare pressure drop (head losses) estimated from theory with that from experiment in each accessory. And then discuss which factors caused the error.

Straight pipe(10A, 15A, 20A)
Straight pipe which is 0.01m diameter has = 524m, and = 0.274m. At the 15A straight pipe, = 0.0763m, and = 0.048m. Values of head loss are = 0.0193m, and = 0.006m in the 20A straight pipe.
Each error factor is 47.7%, 37.1%, and 68.9%.
