Use the worked example above to you solve this problem. a hiker begins a trip by first walking 25.5 km southeast from her base camp. on the second day she walks 42.0 km in a direction 60.0° north of east, at which point she discovers a forest ranger's tower. (a) determine the components of the hiker's displacements in the first and second days. ax = km ay = km bx = km by = km (b) determine the components of the hiker's total displacement for the trip. rx = km ry = km (c) find the magnitude and direction of the displacement from base camp. magnitude km direction ° north of east

Air enters a gas turbine with two stages of compression and two stages of expansion at 100 kpa and 17°c. this system uses a regenerator as well as reheating and intercooling – the intercooler returns the air to the inlet temperature. the pressure ratio across each compressor is 4 ; 300 kj/kg of heat are added to the air in each combustion chamber; and the regenerator operates perfectly while increasing the temperature of the cold air by 20°c. determine the system’s thermal efficiency. assume isentropic operations for all compressor and the turbine stages and use constant specific heats at room temperature.
