WebHigh temperature thermoplastic resins are generally classified by a continuous use temperature (CUT) or relative thermal index (RTI) of greater than 150°C. These temperatures are considered to be the maximum useful service temperature for materials where a critical property will not be unacceptably compromised through thermal degradation. WebTherefore, the amount of heat in the flash steam and condensate must equal that in the initial condensate of 671 kJ. Steam tables give the following information.. Total enthalpy of saturated water at atmospheric pressure ( hf) = 419 kJ/kg. Total enthalpy in saturated steam at atmospheric pressure ( hg) = 2 675 kJ/kg.

Web18 May 2015 · Suppose you have to find all properties of steam at 150. Then first of all use temperature scale. Find out in the temperature where 150 is. Then mark it and put a scale across it covering the entire row. This entire row will give you all the properties corresponding to this temperature. Fig. in this way, we can get all the properties, . So from ... WebThis pressure is given by the saturated vapour pressure, and can be looked up in steam tables, or calculated. As a guide, the saturated vapour pressure at 121 °C is 200 kPa, 150 °C is 470 kPa, and 200 °C is 1,550 kPa. The critical point is 21.7 MPa at a temperature of 374 °C, above which water is supercritical rather than superheated. Above ...
