A turbine salesman makes the following claim for one of his products

A turbine salesman makes the following claim for one of his products: Steam enters a steady-flow adiabatic turbine at 4 MPa, 600 °C with negligible velocity and exhausts at 200 kPa with a velocity of 180 m/s. The flow rate is 2.2 kg/s and the turbine power is 2 MW. a. If the turbine operated as described by the salesman, what would the temperature of the exhaust steam be? b. Could the salesman’s claim be valid? Explain and justify your response. (Hint: look at the Clausius Inequality.)

Dynamics Projectile Problem

A hunter in the plains of Africa is equipped with a bow and arrow. The maximum range of the bow is 100 m. If a Lion charges straight towards him at 30 km/h and the hunter aims his bow at 20 degrees relative to the horizontal, find: (a) time of flight of the arrow (b) arrow velocity (c) how far away should the lion be when the hunter releases the arrow (d) the radius of curvature of the arrow 1.5 seconds after the launch

Finding the differential reading height

See attached file for full problem description. A U-tube mercury manometer is connected to a closed pressurized tank as illustrated in the Figure below. If the air pressure is 2 psia, determine the differential reading (height) h. The specific weight of the air is negligible. Assume fluids are at room temperature.

Flow rate

Water flows through the pipe contraction shown in the figure below. For the given 0.2 m difference in the manometer level, determine the flowrate as a function of the diameter of the small pipe, D. See attached file for full problem description.

Thermal conductivity

1. The composite wall of an oven consists of three materials, two of which are of known thermal conductivity, kA = 20 W/m•K and kC = 50 W/m•K, and known thickness, LA = 0.30 m and LC = 0.15 m. The third material, B, which is sandwiched between materials A and C, is of known thickness, LB = 0.15m but the thermal conductivity kB is unknown. Under steady-state operating conditions, measurements reveal an outer surface temperature of Ts,o = 20 °C, an inner surface temperature of Ts,i = 600 °C, and an oven air temperature of T∞= 800 °C. The convection coefficient h inside the oven is known to be 25 W/m2•K. What is the value of kB? See attached file for full problem description.
