PROBLEM #2 (68 pts.) Steam at 200 psia, 600°F (State 1) enters an adiabatic turbine cperating at steady state with a mass flow rate of 16.5 lbm/min and exits at 15 psia, 240°F (State 2), Neglecting the changes in kinetic and potential energies and assuming the surroundings to be at T.- 537 R. Determine: a) the actual power output, in Btu/min. b) the reversible (or maximum) power output, in Btu/min. c) the rate of exergy destruction, in Btu/min....

Water at 50°F and 20 psia is heated in a chamber by mixing it with saturated water vapor at 20 psia. If both streams enter the mixing chamber at the same mass flow rate, determine the quality of the exiting stream to 3 significant digits (don't forget a leading o if needed). Mixing section

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...

A portion of an ammonia (NH) refrigeration cycle is shown in the figure below. Two streams enter a mixing chamber with one exit stream. One stream with mass flow rate my firsts enters a heat exchanger at Ti= 30 °C (state 1), is cooled to 15 °C (state 2) and then enters the mixer. The rate of heat transfer from the water side of the heat exchanger, Q7, is 100 kJ/s. The second stream with mass flow rate na -2...

1) A water fountain is to be installed at a remote location by attaching a cast iron pipe directly to a water main through which water is flowing. The entrance to the pipe is sharp-edged 15m (K-0.5), and the 15m long piping system involves three 90 bends without vanes (K1.1), a fully open gate valve (K.-0.2), and a fully open angle valve (K-5). If the diameter of the pipe is 2 em and the system is to...

The figure shows a schematic of a power plant that has two steam turbines. The water (the working fluid for the plant) leaves the high pressure turbine (HPT) as saturated vapour at 1000 [kPa]. Part of this flow is diverted to an insulated heat exchanger, which uses a hot air stream to create superheated steam that enters the low pressure turbine (LPT). The air mass flow rate is me=19.5 kg/s) and the air temperature drops from 1100 to 600°Cas it...
