Determine the following for a humid air stream at 1 atm if the enthalpy deviation is - 0.6 kJ/kg dry air and the wet bulb temperature is 30 °C. Use the attached psychrometric chart. a. What is the dry bulb temperature? b. What is the humid volume? c. What is the dew point temperature?

5. Solar ponds are small artificial lakes used to store solar energy. The rise of heated (and thus less dense) water to the surface is prevented by adding salt at the pond bottom. In a typical salt gradient solar pond, the density of water increases in the gradient zone, as shown. For H 4 m, po 1040 kg/m³, and a thickness of 0.8 m for the surface zone, calculate the gauge pressure at the bottom of the gradient zone. V S Sun = = H=4m = Surface zone Po 1040 kg/m³ Increasing salinity and density Gradient zone Storage zone - (2 Po=1040 kg/m P= Po(1+35+5²)

Estimate the thermal conductivity of tomato juice at 35 ° C. (Water content = 87.0% wet basis). Thermal conductivity of material = AnswerW / m ° C

the pressure drop across the tube bank, and (c) the rate of condensation of steam inside the tubes. Evaluate the air properties at an assumed mean temperature of 35°C and 1 atm. Is this a good assumption?solve this part too
