Can somone show me how to do the 1st problem? Need to
find the LS and SS for the fit and the LH and SH for the hole.
Fits are all SHAFT BASIS METRIC but the shaft and hole diameters can not be used right out of the table. This is because the 3mm shaft tolerance does not match. You will need to lookup the "Fit" from the table, and then use the LS (Largest Shaft) and SS (Smallest Shaft)...

174 2 combustor , =1500 K Problem 2 (22 pts): Brayton cycle and entropy calculations An open Brayton cycle is used to generate electricity. Air enters the isentropic compressor at T1 = 300 K and P1 = 100 kPa with a mass flow rate m = 1.5 kg/s. The combustor can be modeled as a constant-pressure heat exchanger, supplying 1540 kW of thermal power to the air from a thermal reservoir (Th = 1750 K). Air enters the isentropic turbine...
