Prediction of accurate values of enthalpy (H) or enthalpy departure (H ) for gases is very important in process design calculations and other industrial applications.Experimental measurements of enthalpy or enthalpy departure for superheated vapor are not easy to perform.
Abundant data on the momentum, heat and mass transfer is available in the literature. Most of this data is confined to impermeable surfaces. It is known from studies concerning flat plates that blowing into the boundary layer can severely reduce the transport coefficients (friction factor,mass and heat transfer coefficients). This work studies the influence of blowing on the friction factor and mass transfer
The corrosion of carbon steel in agitation systems of single phase (1% wt. NaCl solutions) and two phases (1% wt.NaCl solutions / Kerosene) were investigated by weight loss and polarization techniques. In single aqueous phase the weight loss experiments were carried out at different rotational velocities (262, 349, 438, 525, 600, 612, 800, 1000, 1200 and 1400) rpm using circle disk turbine agitator of 8 cm diameter.The average corrosion rate increased with increasing rotational speed.
