Consider the following C program: #include #include int main() { printf("%d\n", getppid()); while(1) {} } Suppose that we execute the program in the background with the command './a. out &'. This gives us the ability to run the ps command while the C program is executing. The following is displayed by the ps command: PID TTY STAT TIME COMMAND 9489 pts/0 Ss 0:00 -tcsh 10314 pts/0 R 0:14 ./a. out 10320 pts/0 R+ 0:00 ps a What is printed by the C program?

Apump is used to circulate hot water in a home heating system. water enters the well-insulated pump operating at steady state at a rate of 0.42 gal/min. the inlet pressure and temperature are 14.7 lbf/in.2, and 180°f, respectively; at the exit the pressure is 60 lbf/in.2 the pump requires 1/15 hp of power input. water can be modeled as an incompressible substance with constant density of 60.58 lb/ft3 and constant specific heat of 1 btu/lb or. neglecting kinetic and potential energy effects, determine the temperature change, in °r, as the water flows through the pump.
