- Homework Statement
- What is the speed of the jet in terms of T1,TZ and T
- Relevant Equations
- delta Q = mC delta T
or
delta Q = c delta T , where c is specific heat capacity
In answering questions (a.) Why heat intake in this system is
## \Delta Q_{sys} = ( \Delta Q_{hot water} + \Delta Q_{cold water} ) / 2 ##
where.
##\Delta Q_{hot water} = c(T_1 - T_f) ##
##\Delta Q_{cold water} = c(T_2 - T_f) ##
I think T or T_f should be between T_1 and T_2
But why is the ##\Delta Q_{sys}## multiplied by a factor of 1/2?
