Consider a packed bed of 10cm diameter concrte (stone mix) spheres to be used as a thermal (energy) storage sysytem initailly the speheres are 15 deg C; airat 50deg C flows around each sphere providing a convection coefficeint of 10Wm^-2k^-1. What will be surface temperature of these spheres after 5 hours

the equation above shows how temperature f, measured in degrees fahrenheit, relates to a temperature c, measured in degrees celsius. based on the equation, which of the following must be true?

a temperature increase of 1 degree fahrenheit is equivalent to a temperature increase of

5

9

degree celsius.

a temperature increase of 1 degree celsius is equivalent to a temperature increase of 1.8 degrees fahrenheit.

a temperature increase of

5

9

degree fahrenheit is equivalent to a temperature increase of 1 degree celsius.
