Steam at 260°c and 7.00 bar absolute is expanded through a nozzle to 200°c and 4.00 bar. negligible heat is transferred from the nozzle to its surroundings. the approach velocity of the steam is negligible. the specific enthalpy of steam is 2974 kj/kg at 260°c and 7 bar and 2860 kj/kg at 200°c and 4 bar. use the open-system energy balance to calculate the exit steam velocity

Modify the equation fδt=δ (mv) to find the force of friction.

What makes thermal imaging cameras useful? they can detect differences in color. they can detect differences in wave speeds. they can detect differences in temperature. they can detect mechanical waves.

A3030 cmcm wrench is used to loosen a bolt with a force applied 0.30.3 mm from the bolt. it takes 6060 nn to loosen the bolt when the force is applied perpendicular to the wrench. how much force would it take if the force was applied at a 3030 degree angle from perpendicular? a 3030 cmcm wrench is used to loosen a bolt with a force applied 0.30.3 mm from the bolt. it takes 6060 nn to loosen the bolt when the force is applied perpendicular to the wrench. how much force would it take if the force was applied at a 3030 degree angle from perpendicular?
