Saturated steam at 232.1 kPa and 80% quality is being used to heat a liquid food by direct steam injection. The product enters the heating system at 200 kg/min and 158C, and leaves at 1058C. The specific heat of the product is 3.85 kJ/kgK and does not change significantly during the heating process. Estimate the steam requirement.

To develop this problem we will apply the thermodynamic concepts of the first law, in which we will make a balance of the first law. Then look for me in the thermodynamic tables under the conditions given the values for the enthalpy (Considering the given quality). We will calculate from this the enthalpy of the system and finally we will find the steam requirement

answer: d. a cme increases the amount of energy in the solar wind

explanation:

coronal mass ejections, also called cmes, are large clouds of plasma and magnetic field that erupt from the sun. only when the cloud is aimed at earth will the cme hit earth and therefore cause impacts. high-speed solar wind streams come from areas on the sun known as coronal holes.
