Two charges lie on positive x-axis. Charge A (2.0 x 10-9 C) is 2.0 cm from the origin and Charge B is 4.0 cm from the origin. (-3.0 x 10-9 C). What is the total force exerted by these two charges on Charge C (5.0 x 10-9 C) located at the origin?
A turbine operates under steady flow conditions, receiving steam at the following state: Pressure
1.5 MPa, temperature 185 degree C, enthalpy 2785 kJ/kg, velocity 33.3 m/s and elevation 3 m.
The steam leaves the turbine at the following state: Pressure 22 kPa, enthalpy 2512 kJ/kg, velocity
100 m/s, and elevation 0 m. Heat is lost to the surroundings at the rate of 0.29 kJ/s. If the rate of
steam flow through the turbine is 0.42 kg/s, what is the power output of the turbine in kW?
The energy absorbed by an engine is two times greater than the work it performs.
What is its thermal efficiency?
What fraction of the energy absorbed is expelled to the cold reservoir?
In a water tank there is 12.0 liters of water at a temperature of 44.0 °C. Boiling water at 100.0 °C is poured into the tank until the water is at 90.0 °C. How many liters of boiling water was poured into the tank? The specific heat capacity of liquid water is 4.19 kJ/kg/°C.
