AI Thread Summary
To raise the temperature of 3.5 m³/s of moist air from 10°C to 27°C, specific calculations involving heat transfer and properties of moist air are necessary. The required heat can be determined using the specific heat capacity of air and the moisture content at the initial conditions. After heating, the new relative humidity must be calculated based on the increased temperature and the moisture content. Additionally, the power required for the heating unit can be derived from the total heat added over time. For further assistance, it's recommended to repost in the homework help forum with an attempt at the solution.

Can anyone help me with this?

-How much heat must be added to 3.5 m3 /s of moist air with a dry bulb temperature of 10°C and a relative humidity of 60% to raise the temperature of the air by 17°C?

• What will be the relative humidity of the air once this heat is added?

• What is the power required in the heating unit?

Thread 'Using battery energy to heat a battery…'

Problem: You’re an Uber driver with a Tesla Model 3. Today’s low: 30F, high: 65F. You want to reach a USD$ profit target in the least number of hours, but your choices could have added cost. Do you preheat the battery only when you are headed to the charging station (to increase the charging rate by warming the battery — however the battery might not be “warm enough” when your reach the charger and thus slower charging rates), or do you always “navigate to the charger” the entire day (which...
