    How Does Adding a Nozzle Affect Water Efflux Velocity and Energy Conservation?

    yeah, the mass efflux remains constant. i.e dm/dt=rho*A1*v1=rho*A2*v2 let us consider a interval t for clculating the efflux so that we can write, m=rho*A1*v1*t=rho*A2*v2*t my question is: the K.E in the first case is, K.E1 = m*v1^2/2 (which is = m*g*h by conserving energy) now if the...

    Pressure relief question (thermo)

    the process is isochoric only in case 1 when only the tap to relieve gas has been opened. if you open the taps for gas and water simultaneously, then it would be a polytropic process.

    Pressure relief question (thermo)

    the energy content of the system is given by the enthalpy i.e H=U+PV, it can be considered as sum of enthalpies of the two phases of the closed system i.e Hgas=Ugas+P*(Vgas) Hwater=Uwater + P*(Vwater) (consider mechanical equm) Now 'Ugas' depends on 'Cgas'(specific heat) and Uwater depends...

    How Does Adding a Nozzle Affect Water Efflux Velocity and Energy Conservation?

    nozzle complex! i have a tank having water filled till an elevation 'h'. Now at the bottom of this is a small opening of circular cross-section with a diameter say 'd1'. This arrangement is kept in free atmosphere so a uniform pressure Patm=1.013 bar applies everywhere. This is case 1 and in...
