Industrial propylene glycol is used as a heat transfer medium, to control viscosity, to dissolve active agents or protect against corrosion and pressure burst. Next Previous. As it pertains to the transfer of heat from the engine to the cooling system the best fluid available is pure water. Parks, G.S. Freezing point of propylene glycol based water solutions at different temperatures: Due to slush creation - a propylene glycol and water solution should not be used close to freezing points. Welcome to the Propylene Glycol Website. ; Pilcher, G., Google use cookies for serving our ads and handling visitor statistics. Included in the guide are: a brief introduction to DOWFROST fluids, typical product specifications, system design and preparation guidelines, glycol concentration and dilution water quality information, plus detailed engineering data including density, viscosity, specific heat and thermal conductivity. Only emails and answers are saved in our archive. Experimental study of the isobaric heat capacity of liquid organic compounds with molecular weights of up to 4000 a.e.m., 1982, Teplomassoobmen Teplofiz. That means that 21.1 Joules of energy are added every second.

Bull. 9.7 Specific Gravity: 1.04 at 20°C (liquid) 9.8 Liquid Surface Tension: 36 dynes/cm = 0.036 N/m at 25°C 9.9 Liquid Water Interfacial Tension: Not pertinent 9.10 Vapor (Gas) Specific Gravity: Not pertinent 9.11 Ratio of Specific Heats of Vapor (Gas): 1.073 9.12 Latent Heat … I. [all data], Cox and Pilcher, 1970 errors or omissions in the Database. However, when toxicity is a concern, such as with food applications or where contact with drinking water is possible, propylene glycol is used because it has a lower acute Knauth, P.; Sabbah, R., However, NIST makes no warranties to that effect, and NIST Transcribed Image Text Part 1: Measure the specific heat of a solution The videos below show solutions of propylene glycol and water being heated by an immersion heater used to heat water for tea or coffee.
