Using the program below, identify the values of pid at lines A and C, and the values of pid1 at lines B and D. (Assume that the actual pids of the parent and child are 2600 and 2603, respectively.)

int main() ( pid t pid, pid1; /* fork a child process */ pid = fork(); if (pid〈 0) { /* error occurred */ terinttstdec, "Fork Failed"); return 1; else if (pid == 0) { /* child process printf('' child: Rad = %d", Rid); printf( "child: pidl %d", = pid1); /* B*/ else /*parent process/ pid! = geteid(); printf("parent : Rid-%d", pid); printf("parent : pid! =%d", wait(NULL); pid1); /* D*/

Amass of m 1.5 kg of steam is contained in a closed rigid container. initially the pressure and temperature of the steam are: p 1.5 mpa and t 240°c (superheated state), respectively. then the temperature drops to t2= 100°c as the result of heat transfer to the surroundings. determine: a) quality of the steam at the end of the process, b) heat transfer with the surroundings. for: p1.5 mpa and t 240°c: enthalpy of superheated vapour is 2900 kj/kg, specific volume of superheated vapour is 0. 1483 m/kg, while for t 100°c: enthalpy of saturated liquid water is 419kj/kg, specific volume of saturated liquid water is 0.001043m/kg, enthalpy of saturated vapour is 2676 kj/kg, specific volume of saturated vapour is 1.672 m/kg and pressure is 0.1 mpa.

Line joining liquid phase with liquid and solid phase mixture is known as: a) liquidus b) solidus c) tie line d) none of the mentioned
