Answer:
The minimum mass flow rate will be "330 kg/s".
Explanation:
Given:
For steam,


For water,


They add energy efficiency as condenser becomes adiabatic, with total mass flow rate of minimal vapor,
⇒ 
On putting the estimated values, we get
⇒ 
⇒ 
⇒

only if there signal is turned on
Answer:
230.4W
Explanation:
Heat transfer by conduction consists of the transport of energy in the form of heat through solids, in this case a jacket.
the equation is as follows

Where
Q=heat
k=conductivity=0.04
A=Area=1.8m^2
T2=33C
T1=1C
L=thickness=1cm=0.01m
Q=230.4W
the skier loses heat at the rate of 230.4W

Answer:
int()
Explanation:
float() is using decimals, so that can't be it, like float(input( "how much does this cost?"))
print() is used to print something, not a user asking, like print("hello")
string() means like a whole, like string( I am good)
By elimination, int() is correct.
Hope this helps!
