1. A gas-turbine power plant operates on a modified Brayton cycle. The pressure ratio of the compressor is P2/P.
The atmospheric pressure is Patm (kPa). Air enters the compresor at Tc.in (°C) and each state of the turbine at
Trin (K). The compressor and the high pressure turbine have the isentropic efficiency of 100% and the low pressure
turbine has an isentropic efficiency of 7LPT (%). The high pressure turbine develops just enough power to run the
compressor (WHPT = Wc). If the mass flow rate of the air into the compressor is mair (kg/s) show the cycle on
T - s diagram and determine the power values of the compressor and turbines, the heat input and the cycle efficiency.
Assume constant properties for air c, (kJ/kgK), cp (kJ/kgK).

Select all true statements. ANFO explosive is often preferred because using bulk explosives is cheaper, less labor intensive during loading and they fill the entire blast hole diameter. Emulsion explosives should not be used in strong and massive rocks where a high detonation pressure and high detonation velocity is required to break the rock. During rock fragmentation by blasting, the reflection of the compression wave at the free face into tension and shear waves contributes to additional cracking between the free face and the blast hole. When metals or other reactive elements are present in the composition of an explosive, less oxygen is required for a an oxygen-balanced reaction.
