Un aceite combustible se quema con aire en una caldera. La combustion 825 Kw de energia termica, 70% se transfiere como vapor a los tubos de la caldera que pasa por el horno. Los productos de la combustion pasan del horno a una chimenea a una temperatura de 650°C. El agua entra a los tubos de la caldera como liquido a 25°C y sale de ellos como vapor saturado a 2.0 MPa. a) Calcula la velocidad en kg/h a la cual se produce el vapor.
b) estima la velocidad del flujo volumetrico del vapor producido.

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

conservation of mass

mass before something happens = mass afterwards
