A 1500 kg drawbridge, 5.66 m long, is being lifted by a cable attached to its end. The cable exerts a 10800 N force at a 50.0 degree angle. What is the net torque on the drawbridge?

What is the rate of 12 liters of water moving through a water hose in 4.0 minutes?

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.
