please answer in c++, thank you

Chapter 6.2, Problem 8E Show all steps: Chapter 6.2A Problem (Fluid mechanics) Head loss is a measure of a fluid's reduction in pressure as it travels down a pipeline and is unavoidable because of friction between the luid and the pipe's walls. For all fluids flowing smoothly in any pipe, the head loss is given by the D'Arcy-Weisbach equation: 2E 3E 72 5E GE HL Is the head loss (m). is the pipe's friction coefficient (dimensionless). L is the pipe length (m or ). d is the plpe diameter (m or ft) Vis the fluid velocity in the pipe (m/s or ft/sec). g is the gravitational constant (9.81 m/S2 or 32.2 /sec2) a. Using this formula, write a C++ function named headLoss() that accepts four doubleprecision arguments (one for the pipe length, one for the pipe diameter, one for the nuid's velocity, and one for the friction coefficient) and returns the head loss in meters.

Include the function written for Exercise a in a working program, and verify that your program is working correctly by determining the head loss for a tluid flowing smoothly at a velocity of 4 mis in a pipe with a friction coefficient or 0.02 that's 100 meters long and has a diameter or 0.3 meters. After verifying that your program is working correctly, use it to determine the head loss for a luid Towing smoothly through the same pipe at a velocity of 6 mis. Step-bv-step solution
