Explanation:
#include <iostream>
using namespace std;
int main()
{
char gender; //details for gender and checking
char ans;
do
{
cout<<"Gender (M or F): ";
cin>>gender;
switch(gender)
{
case 'M':
//cout<<"Male."<<endl;
break;
case 'F':
//cout<<"Female."<<endl;
break;
default:
cout<<"Wrong Gender. Please enter again (M or F): ";
cin>>gender;
}
int Weight,Height,Age; //declaration of variables
double bmr;
cout<<"Weight: ";
cin>>Weight;
cout<<"Height (in inches): ";
cin>>Height;
cout<<"Age: ";
cin>>Age;
//bmr calculations for male and female
if (gender = 'M')
{
bmr = 66 + (6.3 * Weight) + (12.9 * Height) - (6.8 * Age);
cout<<"He needs "<<bmr<<" to maintain his weight."<<endl;
cout<<"He needs to eat "<<(bmr/230)<< " candy bars in one day."<<endl;
}
else if (gender = 'F')

Answer:
a) The flow capacity of the fan is 3150 L/min
d) the minimum diameter is 0.11 m
Explanation:
given data:
A = area of residence = 200 m²
h = height of building = 2.7 m
Percentage of air that must be replaced by fresh air is 35%
v = velocity of air in the duct = 5.5 m/s
a) The volume of the entire building is:
The flow capacity of the fan is equal to:
b) The volume flow rate of fresh air is equal to:
