How to calculate TPH (Transactions per hour)?

Q : Target 1800 transactions per 1hr ,  1 Script contain 30 transactions ,  1 Iteration is taking 30 seconds . Calculate pacing?
A:
Step 1:
Calculate the total no of iterations = target transactions/script transactions
 = 1800/30
 = 60 (iterations)
Step 2:
Time for target iteration = Target iteration * 1 iteration time
= 60*30
= 1800 sec
Step 3:
Remaining Time = Target time‐ Target iteration time
 = 3600‐1800
 = 1800sec
Step 4:
Pacing = Reaming time/Target iterations
 = 1800/60
 = 30 sec
