A cooling water system is cooling a lube oil heat exchanger.
Cooling water system surge tank level is being measured using a differential pressure level detector that has been calibrated at the current water temperature in the tank.
A leak in the heat exchanger results in lube oil collecting in the surge tank.

A. higher; more dense
B. higher; less dense
C. lower; more dense
