1. 1.08x106 grams/h of a superheated fluid flows through a pipe in a power plant. The pipe is 1000 cm long, has an inner diameter of 0.05m and a wall thickness of 0.6 cm. The pipe has a thermal conductivity of 0.0017 kW/mK, and the inner pipe surface is at a uniform temperature of 393K. The temperature drop between the inlet and exit of the pipe is 7K, and the constant pressure specific heat of vapor is 2190 J/kgK. If...

1. Water enters the constant 130-mm inside-diameter tubes of a boiler at 7 MPa and 65°C and leaves the tubes at 6 MPa and 450°C with a velocity of 80 m/s. Calculate the velocity of the water at the tube inlet and the inlet volume flow rate. [5-14] 2. Air enters a nozzle steadily at 50 psia, 140°F, and 150 ft/s and leaves at 14.7 psia and 900 ft/s. The heat loss from the nozzle is estimated to be 6.5...

L 2. Steady statemass balance: Water is flowing at steady state in a 0.1 meter-diameter pipe with a maximum velocity (turbulent profile) of 0.3 meters/sec. The pipe then goes through an expansion, to where it is then flowing in a 0.5 meter-diameter pipe, and the flow regime has changed from turbulent to laminar. In the second section of pipe, calculate the velocity as (a) block flow profile (Vavg), and (b) maximum velocity in laminar flow profile? HINT: you will need...

Problem 1: This is textbook problem 4.51 (page 224) Steam at 1800 lbf/in2 and 1100 °F enters a turbine operating at steady state. As shown in the Figure, 20% of the entering mass flow is extracted at 600 lbf/in2 and 500 °F. The rest of the steam exits as a saturated vapor at 1 lbf/in2 . The turbine develops a power output of 6.8×106 Btu/h. Heat transfer from the turbine to the surroundings occurs at a rate of 5×104 Btu/h....
