A single Phase transformer (13.8kV/220v serving a load of 20 amperes. what rating of at circuits breaker to be used of the second side (low voltage)? How about in the primary side (High Voltage)?​

It is reasonable to assume that the bulk modulus of blood is about the same as that of water (2.2 gpa). as one goes deeper and deeper in the ocean, the pressure increases by 10000 pa for every meter below the surface. if a diver goes down 80.0 m in the ocean, by how much does each cubic centimeter of her blood change in volume? give the answer in cubic centimeters (actually one cubic centimeter equals one milliliter).
