Output each floating-point value with three digits after the decimal point, which can be achieved as follows: printf("%0.3lf", yourvalue); ex: if the input is 8 10 5 4, the output is: 1600 6 1600.000 6.750 note that fractions aren't discarded, and that overflow does not occur for the test case with large values.

Apiping systems consists of 6 m of 6-std type k and 12 m of 4-std type k, both drawn copper tubing. the system conveys ethylene glycol at a rate of 0.013 m3/s. the pressure drop across the system is to be calculated. there are two 90° elbows in the 6-in pipe, a reduction from the 6-in pipe to the 4-in pipe and four 90° elbows in the 4-in pipe. all fittings are soldered (same as flanged) and regular. the inlet and outlet of the system are at the same height.
