Questions: Based on the chart below, if a particular exam results in delivery of 75,000 HU to the anode, how long will it take the anode to cool completely?
Transcript text: Based on the chart below, if a particular exam results in delivery of $75,000 \mathrm{HU}$ to the anode, how long will it take the anode to cool completely?
Solution
Solution Steps
Step 1: Locate 75,000 HU on the chart
The y-axis represents "Thousand heat units", so 75,000 HU corresponds to 75 on the y-axis.
Step 2: Trace the cooling curve
Follow the curve from the 75 mark on the y-axis horizontally to the right until it intersects the x-axis.
Step 3: Determine the cooling time
The intersection point on the x-axis represents the time it takes for the anode to cool completely. This point lies just shy of the 15-minute mark.
