2nd question: random variable
3rd question: if the two objects are dropped from the same height they will hit the ground at the same time
A. 2 S O 2, gas, plus O 2, gas, in equilibrium with 2 S O 3, gas.
Answer:
a ) 
b) 
Explanation:
given data:
pressure ration rp = 12
inlet temperature = 300 K
TURBINE inlet temperature = 1000 K
AT the end of isentropic process (compression) temperature is



AT the end of isentropic process (expansion) temperature is



isentropic work is given as

w = 1.005(610.18 - 300)
w = 311.73 kJ/kg
w(turbine) = 1.005( 1000 - 491.66)
w(turbine) = 510.88 kJ/kg
a) mass flow rate for isentropic process is given as


b) actual mass flow rate uis given as


<u>for instance, steel has a higher thermal conductivity than plastic. Hence, the steel plate gives away heat to the ice block faster than a plastic block does. As a result, ice melts faster on a steel plate than on a plastic one. Faster an object draws heat, the colder it feels.</u>
