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?.

Abrake has a normal braking torque of 2.8 kip in and heat-dissipating cast-iron surfaces whose mass is 40 lbm. suppose a load is brought to rest in 8.0 s from an initial angular speed of 1600 rev/min using the normal braking torque; estimate the temperature rise of the heat dissipating surfaces.

Give heat transfer applications for the following, (i) gas turbines (propulsion) ) gas turbines (power generation). (iii) steam turbines. (iv) combined heat and power (chp). (v) automotive engines

A-mn has a cubic structure with a0 0.8931 nm and a density of 7.47 g/cm3. b-mn has a different cubic structure, with a0 0.6326 nm and a density of 7.26 g/cm3. the atomic weight of manganese is 54.938 g/mol and the atomic radius is 0.112 nm. determine the percent volume change that would occur if a-mn transforms to b-mn.
