Se quiere saber la profundidad de un pozo, para ello se deja caer una piedra en el y se registra un tiempo de 4,2 segundos cuando esta toca el fondo. ¿cual es la profundidad del pozo? ¿con que velocidad llega la piedra al fondo del pozo?

Asample of a gaseous substance changes into a liquid

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.
