Answer:
A)cout<<setw(9)<<fixed<<setprecision(2)<<34.789;
B)cout<<setw(5)<<fixed<<setprecision(3)<<7.0;
C)cout<<fixed<<5.789E12;
D)cout<<left<<setw(7)<<67;
Explanation:
Stream Manipulators are special functions for use with the insertion (<<) and extraction (>>) operators on C++ stream objects, while the 'cout' statement outputs content to the standard output device in C++ programming.
setw: specifies the minimum width of the output field
setprecision: defines the number of decimal places for floating-point value formatting.
fixed: sets the format flag for floating-point streams.
left: left-aligns the output.
A) This statement shows the number 34.789 in a field that provides eight character spaces with two decimal precision. cout<<setw(9)<<fixed<<setprecision(2)<<34.789;
B) Here, the number 7.0 is displayed within six spaces with three decimal precision. cout<<setw(5)<<fixed<<setprecision(3)<<7.0;
C) This command prints 5.789e+12 in fixed-point format. cout<<fixed<<5.789E12;
D) This statement left-aligns the number 67 across a field of six spaces. cout<<left<<setw(7)<<67;
Answer:
The power of the pump is 23.09 kW.
Explanation:
Parameters
gravitational constant, 
mass flow rate, 
flow density, 
efficiency of the pump, 
output gauge pressure, 
input gauge pressure, 
cross-sectional area of output pipe, 
cross-sectional area of input pipe, 
height of discharge, 
(evaluated at pump’s maximum height of 1.22 m)
input height, 
hydraulic power of the pump,
Initially, the volumetric flow (Q) needs to be determined
Next, compute the velocity (v) for both input and output
Subsequently, the total head (H) can be calculated
Finally, the computation of pump power is done as follows
The response to this query is 1 * 10 g/mole = 10.
