7.2:Specific Heat and Latent Heat Capacity of Water

Feb 14, 2021 · Specific Heat is a measure of the energy required to heat 1 gram of substance 1° C. Specific heat is recorded in "calories" for mass in grams (and Joules for kg). Figure 7.11 compares the specific heat of various metals to the specific heat of ice, water, and steam. H-2 SPECIFIC HEAT CAPACITY - Lock Haven(1) The British Thermal Unit of specific heat capacity, (BTU), still used by some engineers, is defined to be the amount of heat required to raise one pound of water one degree Fahrenheit. That is, H = WsT, where W is the weight in pounds, H is in calories, T is in degrees Fahrenheit and s is the specific heat capacity in BTU. The specific heat capacity of water is taken to be numerically equal to one.

Oct 16, 2011 · = steam mass flow (kg s 1). h fg = latent heat of steam (kJ kg 1). x = dryness fraction of steam. c = specific heat capacity of water (4.183 kJ kg 1 K 1 for fresh water). h 0 = overall heat transfer coefficient (kW m 2 K 1). t 1 = water inlet temperature (°C). t 2 = water outlet temperature (°C). t s = steam saturation temperature (°C). C t = velocity of water in tubes (ms Online calculation of properties of water and steamdensity steam, dynamic viscosity steam, kinematic viscosity steam, specific inner energy steam, specific enthalpy steam, specific entropy steam, specific isobar heat capacity cp steam, specific isochor heat capacity cv steam, adiabatic exponent or isentropic exponent kappa steam, thermic conductivity steam, speed of sound steam. Properties of Saturated Steam - Pressure in BarThe total specific enthalpy for steam at 0 bar gauge is:h s = (417.51 kJ/kg) + (2257.92 kJ/kg)


Nov 06, 2015 · This difference in heat rise is known as specific heat. Fig. 3 The specific heat table shows how much heat is required to raise the temperature of several different substances 1°F. Specific heat is the amount of heat necessary to raise the temperature of 1 lb of a substance 1°F. Every substance has a different specific heat. Steam (thermal properties) entropy enthalpy volume Specific Heats:Specific heat capacity for 1kg of steam at 450°C and constant volume is calculated thus:c p = 2094 J/kg/K (Fig 5) c v = c p - R = 2094 J/kg/K - 461.523718 J/kg/K = 1632.476282 J/kg/K and the ratio of specific heats () is calculated as follows: = Steam Tables Calculatorpsi. Specific gas constant:R = 0.461526 kJ/ (kg·K) Specific gas constant:R = 0.1102336 Btu/ (lb·°F) 2. 1. Thermodynamic Properties - Main. Temperature. t.

The excess energy = 2 741.7 - 2 706.7 = 35 kJ/kg, and this is used to raise the temperature of the steam from the saturation temperature of 120 °C to 136 °C. The degree of superheat can be determined either by using superheated steam tables, or by using a Mollier chart. TEMPERATURE & HEAT Specific heat Phase change & How much heat is released from 50g of water as it (a) Changes from liquid to ice at 0oC. (b) Changes from steam to liquid water at 100oC. Q = mL f Q = mL v = 0.05kg*335 kJ/kg = 16,750J = 0.05kg*2260kJ/kg = 113,000J Steam to water transition liberates more heat than water-ice transition.
