An experimental study in condensation has been conducted to analyse the condensation phenomena. The enhancement heat transfer performance is as always highlighted phenomenon for being investigated. The modified surface is a common method for enhancing the performance of condensation since inducing the droplet on the surface. The droplet leads to increasing heat-transfer area, decreasing thermal resistance, and shorten the condensing cycle. The condensation by using water successfully induces droplets on the surface and enhances the heat transfer. But water and refrigerant have different fluid properties which induce different phenomena whereas refrigerant is widely used in industry. In this case, the condensation is conducted on the modified surface by using a commercial promotor to investigate the phenomena. The investigation results show that the surface tension immensely influences the condensate on the surface. Refrigerant is low surface tension fluid which leads to the difficulty of fluid for inducing droplets and almost no enhancement heat transfer performance since the results almost fitted well to Nusselt bare tube prediction around 2443-3063 W/m2 oC with subcooled temperature 2 up to 5 oC.

“…This miniplant focuses on pressure management before and after the customer's home meter and controlling the flow against pipe leaks that can result in financial losses. The pressure is measured using the SKU237545 pressure sensor which is connected to the microcontroller so that the sensor readings can be displayed [12]. In the miniplant there is a YF-S201 flow sensor to determine the amount of water flowing in the pipe [13].…”

The distribution of water through pipes experienced an average water loss of 35%. This is caused by a lack of pipe management, measurement tool management, and pressure management. In this study, a drinking water company miniplant was made using PVC pipe as a simulation to show the action of the solenoid valve as a pressure controller and water flow rate against leakage. This study monitors pressure differences and flow rates. Global valve acts as an actuator to control flow pressure while ball valve acts as an actuator to control flow rate. The results of the validation of the pressure sensor, on average the four sensors produce an accuracy of 99.587% and an inaccuracy of 0.413%. The results of the flow sensor validation, the average of the four sensors produces an accuracy of 97.558% and an inaccuracy of 2.442%. The results of system testing on the solenoid valve pressure control, work according to the set point in controlling pressure. The results of system testing on the solenoid valve pipe leakage control, work according to the set point in controlling pipe leakage but the ratio is high. The ratio is too high because the flow after the solenoid valve is getting slower, but the flow before the solenoid valve is still moving to fill the empty space in the pipe until there is no water flow.

“…Liu et al [26] investigated the flow behaviour and impact of high-pressure CO2 (8 -10 MPa) jet discharges with respect to different nozzle sizes (3 -20 mm) and found that the effect of the released jet represents the main hazard in case of pipeline leakage. Gu et al [27] performed an experimental campaign on a 14.9 m long pipeline with a 15 mm internal diameter to explore the accidental leakage behaviour of CO2 under different conditions (5 -8.5…”
