You buy a magnifying glass at the store. the lens in the magnifying glass is a double convex lens, a lens with two convex curved surfaces. you determine the focal length of the lens is +25 cm. of both sides of the lens have about the same radius of curvature and the lens is made of a glass with index of refraction 1.6, what is the radius of the glass surfaces?

Steam is generated in a boiler of a cogeneration plant at 10 mpa and 450°c at a steady rate of 5 kg/s. in normal operation, steam expands in a turbine to a pressure of 0.5 mpa and is then routed to the process heater, where it supplies the process heat. steam leaves the process heater as a saturated liquid and is pumped to the boiler pressure. in this mode, no steam passes through a condenser, which operates at 20 kpa. (a) determine the power produced in the turbine and the rate at which process heat is supplied in this mode. (b) determine the power produced in the turbine and the rate of process heat supplied if only 60 percent of the steam is routed to the process heater and the remainder is expanded to the condenser pressure.
