During an ifr cross-country flight you picked up rime icing which you estimate is 1/2" thick on the leading edge of the wings. you are now belowthe clouds at 2000 feet agl and are approaching your destination airport undervfr. visibility under the clouds is more than 10 miles, winds at the destination airport are 8 knots right down the runway, and the surface temperature is 3 degrees celsius. you decide to*
a. use a faster than normal approach and landing speed.
b. approach and land at your normal speed since the ice is not thick enough tohave any noticeable effect.
c. fly your approach slower than normal to lessen the 'wind chill' effect and break up the ice

The first law of thermodynamics states that heat added to a system is neither created nor destroyed but is transformed ⇒ as it changes into other forms of energy.

In a steady-flow steam power plant system, two adiabatic high-pressure and low-pressure turbines ane used to generate power. superheated steam enters the high-pressure turbine at 8 mpa and 550°c. the steam expands in the high-pressure turbine to a saturated vapor at 3 mpa. in order to increase the powe generation of the power plant, another steam turbine working in a lower pressure ranges is deployed. the outlet vapor from the first turbine is heated up at a boiler to the temperature of 500 c at the constant pressure of first turbine's outlet (3 mpa). then, the vapor enters the second turbine and produces extra work. the exit conditions of the second turbine are 5o kpa and 90 percent quality. if the total power output of the power plant is 25 mw, determine a) the mass flow rate of the water (kg/s). b) heat transfer rate in the boiler (mw).
