a gas turbine is designed to produce 3000hp when using air at a maximum inlet temperature of 650k and assuming a heat loss of 70 kj/s. if the exhaust temperature is desired to be no greater than 200 degrees celsius, determine the mass flow rate of air required.
in the textbook the only things i can find are this formula
Qadd = mcp(t3-t2)
or Qrej = mcp (t1-t4)
but the problem is that solving with these with Qadd/cp(t3-t2) im not sure if that would be correct using the figures given in this problem because it gives you an exhaust temperature and a max inlet temp.
The Attempt at a Solution
im having trouble coming up with the needed equation to determine the mass flow rate. any infromation would be highly appreciated as to the formula needed to find the mass flow rate.
