Two-phase flow is a flow involving two different fluids flowing simultaneously in a channel. The characteristics of two-phase flow are more complex than single-phase flow because they are influenced by phase interaction, phase distribution, superficial velocity, and friction occurring during the flow process. These interactions cause pressure distribution changes along the pipe and require further investigation to understand the pressure characteristics in air–water two-phase flow. This study object to analyze the pressure distribution of air–water two-phase flow and determine the effect of water and air flow rate variations on pressure distribution using a 1-inch horizontal plexyglass pipe. The research was conducted experimentally using water and air as working fluids. Water flow under variations from 5–13 gpm and air flow rates ranged from 10–50 lpm. The experimental setup consisted of a water pump, air compressor, water flowmeter, air flowmeter, mixer, pressure gauges, and several pressure tapping points installed the pipe were P1 to P5 to measure pressure distribution. Water and air flowed simultaneously through the pipe and passed through a mixer before entering the observation section. Pressure data obtained from each measuring point were then used to calculate absolute pressure, gas and liquid superficial velocities, gas-liquid ratio, void fraction, mixture density, and total headloss. The results showed that increasing air flow rates caused an increase in pressure and pressure gradient along the pipe. The highest pressure value occurred at point P1 with a value of 116,5257 kPa at superficial velocities of Jl = 1.6194 m/s and Jg = 1.6487 m/s, while the lowest pressure value occurred at point P5 with a value of 102,9921 kPa at Jl = 0.6229 m/s and Jg = 0.3297 m/s. Higher superficial velocities of water and air also increased the total headloss thus causing a pressure drop. Pressure distribution tended to decrease along the flow direction, while pressure drop became larger at higher air flow rates. In addition, the ratio of gas superficial velocity to liquid superficial velocity (Jg/Jl) affected the pressure distribution characteristics in two-phase flow. Higher gas-liquid ratios intensified phase interactions, resulting in greater pressure fluctuations and energy losses.
