1. Pressures up to 3000 atm are to be measured with a dead-weight gauge. The piston
diameter is to be 1/8 in. What is the approximate total mass of “weights”which
must be provided for use with this guage? [8+8]
2. Steam is flowing through a horizontal, well-insulated 3-in. - ID iron pipe, 1500 ft
long. The velocity at the entrance to the pipe, where the steam is dry and saturated
at 150 psia, is 100 ft/sec. The steam discharges from the exit of the pipe into an
adiabatic reversible turbine which exhausts at 14.7 psia. The steam leaving the
turbine is in the dry-saturated condition.
