##### Reference no: EM13704099

A steam power plant operates on a simple ideal Rankine cycle between the pressure limits of 3 MPa and 50 kPa. The temperature of the steam at the turbine inlet is 300 C and the mass flow rate of steam through the cycle is 35 kg/s. Show the cycle on a T-s diagram with respect to saturation lines and determine a) the thermal efficiency of the cycle and b) the net power output of the power plant.

#### Show how wave radius must vary with time

He assumed that the blast wave radius R was a function of energy released E, air density , and time t. Use dimensional reasoning to show how wave radius must vary with time.

#### Determine critical clearing time and critical clearing angle

Determine the critical clearing time and critical clearing angle for the hydro and steam units using only the sin δ terms of the approximate transient torque-angle curve.

#### Determine stress in sections and overall change in length

A duralumin tie bar of diameter 40 mm and length 600 mm carries a tensile load of 180 kN. If the bar contains a 30 mm diameter hole along 100 mm of its length, determine the

#### Determine the equivalence ratio

The components of the exhaust gas of a spark-ignition engine using a fuel mixture represented as C8H17 have  a dry molar analysis of 8.7% CO2, 8.9% CO, 0.3% O2, 3.7% H2, 0.3

#### Individual gas and liquid mass transfer coefficients

A mass transfer tower operating at 1 atm and 300 K uses water, which enters free of ammonia at the top, to reduce the ammonia (NH3) concentration in air exhausted from a react

#### Estimate the operating temperature of the board

Atmospheric air at a volumetric flow rate of 0.060 m3/s and 27°C is drawn through the sinks by a blower. Estimate the operating temperature of the board and the pressure dro

#### At what rate will it lose heat to surrounding air

The top of a car has an area of 4 m2 and is at a temperature of 40 C. It’s speed is 40 mph. At what rate will it lose heat to surrounding air at 10 C if heat transfer coeffici

#### Determine heat rejection rate to the surrounding

R-134a enters the condenser of a refrigerator at 800kPa and 50oC at a rate of 0.018kg/s and leaves at 800kPa as a saturated liquid. It is known that the compressor consumes 1.
