Chain Drive Parameter Calculation:

Design a suitable roller chain drive for the following application:

A $40$hp electric motor drives a two$-$cylinder pump. The motor rotates at

$900$ rpm while the pump rotates at $300$ rpm $.$ Assume heavy shock

conditions.$($the numbers written inside the chart are the ANSI sizes of chain the numbers written inside the chart are the ANSI sizes of chain$)$

a$)$ Calculate the design power considering the service factor as a safety

factor.

b$)$ Select a suitable chain size for the given condition.

c$)$ Select the small sprocket tooth number.

d$)$ Select the large sprocket tooth number.
