SE DEBE CONTRUIR UNA PARED QUE TENDRA 4 METROS DE LARGO POR 3 METROS DE ALTO. SI SE UTILIZARAN LADRILLOS HUECOS Y TENIENDO EN CUENTA QUE ENTRE LADRILLO Y LADRILLO SE DEBE COLOCAR ALREDEDOR DE DOS CENTÍMETROS DE MEZCLA PARA UNIRLOS….. ¿ CUANTOS LADRILLOS SERAN NECESARIOS APROXIMADAMENTE PARA CONTRUIR LA PARED?.

Two flowing streams of argon gas are adiabatically mixed to form a single flow/stream. one stream is 1.5 kg/s at 400 kpa and 200 c while the second stream is 2kg/s at 500 kpa and 100 ? . it is stated that the exit state of the mixed single flow of argon gas is 150 c and 300 kpa. assuming there is no work output or input during the mixing process, does this process violate either the first or the second law or both? explain and state all your assumptions.

On a average work day more than work place firs are reorted

Ariver flows from north to south at 8 km/h. a boat is to cross this river from west to east at a speed of 20 km/h (speed of the boat with respect to the earth/ground). at what angle (in degrees) must the boat be pointed upstream such that it will proceed directly across the river (hint: find the speed of the boat with respect to water/river)? a 288 b. 21.8 c. 326 d. 30.2
