Answer:
Number of slices of pizza is 993.
Explanation:
It is given that, in one slice of "everything" pizza there are 650 Calories. The conversion factor from calories to joules is :
1 calorie = 4.184 joules
650 calories = 2719.6 joules
Total energy in the pizza, E = 2700000 J
Let there are n number of slices of pizza. It is given by :
n = 992.79
or
n = 993
So, there are 993 slices of pizza. Hence, this is the required solution.
Answer:
a) 2.33 m/s
b) 5.21 m/s
c) 882 m³
Explanation:
Using the concept of continuity equation
for flow through pipes
Where,
A = Area of cross-section
V = Velocity of fluid at the particular cross-section
given:
a)
substituting the values in the continuity equation, we get
or
or
b)
substituting the values in the continuity equation, we get
or
or
c) we have,
Discharge
thus from the given value, we get
Also,
Discharge
given time = 1 hour = 1 ×3600 seconds
substituting the value of discharge and time in the above equation, we get
or
volume of flow =
