# For the electric circuit, given that c1=0.1 microf, c2=0.1 microf, c3=0.3 microf, and c4=0.3 microf and the total voltage drop across capacitors c1 and c2 at t=0 is v1(0)+v2(0)=120v, what is the initial energy stored in the capacitors network, w(t=0, total)?   ### Another question on Engineering Engineering, 03.07.2019 12:30
Heat is added to a piston-cylinder device filled with 2 kg of air to raise its temperature 400 c from an initial temperature of t1 27 cand pressure of pi 1 mpa. the process is isobaric process. find a)-the final pressure p2 b)-the heat transfer to the air. Engineering, 03.07.2019 12:30
Apiston-cylinder with a volume of 0.25 m3 holds 1 kg of air (r 0.287 k/kgk) at a temperature of 100 c. heat transfer to the cylinder causes an isothermal expansion of the piston until the volume triples. how much heat is added to the piston-cylinder? Engineering, 04.07.2019 17:20
Water vapor initially at 10 bar and 400 °c is contained within a piston-cylinder assembly. the water lost heat to the surrounding according to isochoric (iso-volumetric) process until its temperature is 150 °c. the water is then condensed isothermally to saturated liquid. for the water as a system, calculate the work in kj/kg Engineering, 04.07.2019 17:20
