Can someone please help me with this question?
The time-temperature curve used in fire-resistance tests to assess the fire performance of structural elements, varies according to the test specifications used.
In the ISO 834 specification the temperature T (in degrees centigrade) is defined by:
T=345*log10((8*t+1)+T0)
where t is the time in minutes, and T0 is the ambient temperature in degrees centigrade.
The ASTM E119 curve is defined as follows for T (also in degrees centigrade)
T=750(1-e^(-3.79553√(th)) )+170.41√(th)+T0
where th is the time in hours, and T0 is the ambient temperature in degrees centigrade.
Write a function that asks the user to select the specification they prefer, and then input all required values in their correct units, taking into account the specification selected. The temperature T is calculated and then displayed from code within the function, and as part of a readily understandable statement in English.
