A river has a catchment area of 290 km² and study shows that the site has an average annual rainfall of 193 cm. It is proposed to develop the site by the installation of two (2) units of turbine-generator set the capacity of one is twice the capacity of the other. If the over-all efficiency of both units is 84%. Calculate the electric power that can be generated by each unit.

Fix one end of it on 150c and make the other end tangent to a piece of iron of 8cm length and equal to it with the cross-sectional area and straight to one, and the temperature of the piece of iron was 20c. Calculate the contact point temperature between the two pieces, noting that the thermal conductivity coefficient of copper is Scmc / [0.85, while for iron it is 0.75] / ScmC.
Question 3.3 When the air with a pressure of 0.1 MPa and a specific volume of 0.8 m³/kg was provided into a compressor at a flow rate of 0.25 kg/s, its pressure became 0.7 MPa and its specific volume became 0.2 m³/kg. Through the compression, the specific internal energy was increased by 80 kJ/kg, and there was heat loss of 50 kJ/s to the environment. In this case, calculate the work [k]/s = kW] that the compressor did in unit time. Potential energy and kinetic energy can be negligible.
