The water vapor that is 3.00 MPa and 540°C goes through a pipe with a 0.40 m^2 cross sectional area and a 8.20 kg/s mass flow rate. At what s

20.3 cm diam 2.44 m 1.22 m Water Air at 105 kPa and 37°C flows upward through a 6-cm-diameter inclined duct at a rate of Q (L/s). The density of air at this temperature and pressure is 1.10 Kg/m³. The duct diameter is then reduced to 4 cm through a reducer. The pressure change across the reducer is measured by a water Air manometer. The elevation difference between the two points on the pipe where the two arms of the manometer are attached is 0.20 m. Determine the differential height between the fluid levels of the two arms of the manometer. Q (L/s) 90

Determine the electrical power supplied to a boiler when the temperature of the entering water is 20 C and the exiting temperature is 89 C. The flow of.the pressured water is 2 Kg/s. There is a negligible pressure drop through this boiler and it operates at a constant pressure of 3 bars. The specific heat is c = 4,370 J/(Kg K). There is a 150000 W rate of heat loss from the boiler during this process to a surrounding at 293.2 k. Consider steady state conditions. Calculate the total rate of entropy production. Calculate the total rate of exergy destruction (W)  The dead state temperature is 293.2 K and pressure is 1 bar.

A water is flowing through the duct having daimeter 15 cm and length 15 m. The inlet temperature of water is 100 °C & exit temperature is 5 °C respectively. Calculate the mass flow rate of water through the duct in mol/sec by considering heat transfer due to convection. Individual heat transfer coefficent is 15 w/m2K.
