Question

A student studying in medical school, according to the body structure of a person with high fever, the body
will help calculate the time required to lower the temperature to a certain degree
wants you to develop a formula.
Heat produced in the human body 400 W, total heat passing through the body through transmission, convection and radiation
If 800 W and body specific heat 3500 kJ / kgK, other students may also need other features.
By choosing according to your own body structure, the time to lower the body temperature by 10 o C.
You calculate.

size=180cm

weight=93

Answer 1

Note: Heat produced by the normal human body resting is between (100-200)W--- not what you mentioned---(but this data is of no use as you want to lower the body temperature by T = 10 °C)

Given, Heat in th body due to hot fever, Q = 800 W = 800 J/s                        

Body specific heat, c = 3.5 kJ/kg K = 3500J/kg K (Note: kindly check this data in internet your one mentioned is wrong)

Mass of the Body, m = 93kg

We need to lower the body temperature by, T = 10 °C

We Know, Q = M x c x T

where M is in Kg/sec, so here M = m/t
