Use the mouse to move the wood block in and out of the water and watch what happens to the liquid level (boxed in yellow in the picture) and how the buoyant force changes (pink arrow that appears on the box when it is in the water). when moving the wood block deeper into the water the water level increased. what happened to the buoyant force?

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.
