A plant operates under steady-state conditions. Sea water enters the plant with a mass flow rate of 1000 kg/hr and a density of 1030 kg/m³. Brine (i.e., a high- concentration solution of salt in water) exits at 150 kg/hr with a density of 1250 kg/m³. Water vapor also exits the plant at a pressure of 125 kPa and a temperature of 115°C. The water vapor can be modeled as an ideal gas with Rvapor = 461 J/(kg-K). 1 Seawater

b.) Calculate the volumetric flow rate of the water vapor leaving the plant, in m^3/hr.

c.) Calculate the volumetric flow rate of the brine, in m^3/hr.

A plant operates under steady-state conditions. Sea
water enters the plant with a mass flow rate of 1000
kg/hr and a density of 1030 kg/m³. Brine (i.e., a high-

with a density of 1250 kg/m³. Water vapor also exits the
plant at a pressure of 125 kPa and a temperature of
115°C. The water vapor can be modeled as an ideal gas
