A food-services company with a 480 V, three-phase service entrance has the following set of loads:  A 7 ton walk-in refrigerati

on unit:3 COP of 1.2 and 0.78 lagging power factor  A conveyor belt system consisting of 10 continuous-duty induction motors: each 5 HP, 81% efficient, PF = 0.73 lagging  A 20 kVA T8 fluorescent lighting system with electronic ballasting (PF = 0.93 leading)  A 75,000 BTU/hr food dehydrator4 Consider the case when all systems are fully loaded. Calculate the reactive power required to compensate this customer’s load to a 0.95 lagging power factor.

natima [27]

Answer:

Final mass of Argon=  2.46 kg

Explanation:

Initial mass of Argon gas ( M1 ) = 4 kg

P1 = 450 kPa

T1 = 30°C = 303 K

P2 = 200 kPa

k ( specific heat ratio of Argon ) = 1.667

assuming a reversible adiabatic process

<u>Calculate the value of the M2 </u>

Applying ideal gas equation ( PV = mRT )

P₁V / P₂V = m₁ RT₁ / m₂ RT₂

hence : m2 = P₂T₁ / P₁T₂ * m₁

                   = (200 * 303 ) / (450 * 219 ) * 4

                   = 2.46 kg

<em>Note: Calculation for T2 is attached below</em>

What Happens If A Sonic Boom Is Created?
Volgvan

Answer:

Explanation:

A sonic boom is a loud sound kind of like an explosion. It's caused by shock waves created by any object that travels through the air faster than the speed of sound. Sonic booms create huge amounts of sound energy. When an object moves through the air, it makes pressure waves in front of and behind it.
