After Oi-eration. 

 First Period — 

 Quantity of air (V) = 33.78 at 690.26 — 32' = 37.26 = t'. 



V + (V X t' X 0.00203,i) = v. V = 1^ = 31.4. W = V x 0.08073 = 2.53

 Rise in temp, of air 5.94 = t. Q = W x t X sp. h. = 2.53 x 5.94 x 0.2374 = 3.5677 = heat given to air. 

 Rise in temp, of water 1.242 x 130.859 = 162.5268 = lieat given to calorimeter. 



3.5677 = lieat given to air. 



Heat dissipated in one hour 166.0945 



Second Period — 

 Quantity of air (V) = 38.3 at 680.8 — 320 = 36.8 = t'. 



V + (V X t' X 0.002035) = V. V = ^^•^- = 35.6. W = V x 0.08073 = 2.87

Rise in temp, of air 4.2 = t. Q = W X t X sp. h. = 2.87 X 4.2 x 0.2374 = 2.8682 = heat given to air. 



Rise in temp, of water 0.864 x 130.859 = 113.0622 = heat given to calorimeter. 



2.8682 ^ heat given to air. 



Hourly dissipation of heat 115.9304

 Loss in hourly dissipation of heat during second period after operation 34.0465 



Heat Production. 



Before Operation. 



Pall of animal temperature in H hour.s 0O.4. in 1 hour 0.267 = t. 



Q = W X t X sp. h. = 18.25 X 0.267 X 0.75 = 3.6555 = heat taken from reserve. 



149.9769 = heat dissipated in one hour. 

 3.6555 = heat taken from reserve. 



Hourly production of heat 146.3214 



After Operation. 

 First Period — 

 Fall of animal temperature in 1| hours OO.o, in 1 hour 0.334 = t. 

 Q= W X t X sp. h. = 18.25 x 0.334 x 0.75 =4.5716 = heat taken from reserve. 



166.0945 = hourly dissipation of heat. 

 4.5716 = heat takeu from reserve. 



Hourly production of heat 161.5229 



Second Period^ 

 Rise of animal temperature in 1 j hours 0O.3, in 1 hour 0.24 = t. 

 Q = W X t X sp. h. = 18.25 x 0.24 x 0.75 = 3.275 = heat added to reserve. 



115.9304 = hourly dissipation of heat. 

 3.275 = heat added to reserve. 



Hourly production of heat 119.2054
