Which outcome occurs in a Boulton-Watt steam engine when the condenser cooling water supply is interrupted?

💡 Explanation

When cooling water is interrupted, vacuum condensation ceases because heat removal stops, leading to higher cylinder backpressure, reducing the effective pressure difference and power output. Therefore, reduced power results, rather than overspeed, jamming, or explosion which involve separate failure mechanisms and conditions.
