Q.	If the two reservoirs are kept at the same level, the head loss is _______
A.	Z1-Z2
B.	Zero
C.	T2-T1
D.	S2-S1
Answer» B. Zero
Explanation: Total head loss for a system is equal to the height difference of the reservoirs. Height difference is denoted by the letter ‘H’. The height difference between the reservoirs is Z1-Z2. Since they are of the same level, Z1=Z2. Therefore, head loss is zero.
