Subtopic: Sensible heating process on psychrometric chart
Question Statement:
In an electric air heater for seed drying, ambient air at $22^\circ\text{C}$ is heated along the shown path to $45^\circ\text{C}$. If the air mass flow is $3.5\text{ kg/s}$ and $c_s = 1.025\text{ kJ/(kg}\cdot\text{K)}$, compute the electrical power consumed by the heater in $\text{kW}$, assuming an efficiency of $95\%$ (round off to one decimal place).
