Problem 271E

A water pump delivers 6 hp of shaft power when operating. If the pressure differential between the outlet and the inlet of the pump is measured to be 1.2 psi when the flow rate is 15 ft3 /s and the changes in velocity and elevation are negligible, determine the mechanical efficiency of this pump.

Step-by-Step Solution:
Step 1 of 3

Implied Powers  McCulloch v. Maryland- an 1819 supreme court decision that established the supremacy of the national government over the state governments. Led by Chief Justice John Marshall, held that Congress has certain implied powers in addition to the powers enumerated in the Constitution.  The Constitution was meant to permit Congress to use all means “necessary and proper” to fulfil its responsibilities.  Set forth two constitutional principles: - Supremacy of the national government over the states. - The national government has certain implied powers that go beyond its enumerated powers.  Enumerated powers – powers of the federal government that are listed explicitly in the Constitution. 
