An accumulator is to be sized to supplement pump delivery during peak demand with 10 liters of fluid between the pressures of 14 MPa and 10 MPa. To be sure that fluid is available from the accumulator at 10 MPa, it is precharged to 8 MPa. What size should the accumulator be if atmospheric pressure equals 101 kPa and the process is consid- ered to be isothermal?

(Problem 11 attached in the image below)

11. An accumulator is to be sized to supplement pump delivery during peak demand with
10 liters of fluid between the pressures of 14 MPa and 10 MPa. To be sure that fluid is
available from the accumulator at 10 MPa, it is precharged to 8 MPa. What size should
the accumulator be if atmospheric pressure equals 101 kPa and the process is consid-
ered to be isothermal?
