    Heat gain from vehicle exhaust?

    Thanks for all the responses & advice. There are 8 vehicles in the workshop, This facility is for vehicle repairing. I assumed 2 Engines working all the day. There is no Exhaust duct to take the vehicle. This facility is fully enclosed there are roller shutters - 3x4 meter this always in the...

    Heat gain from vehicle exhaust?

    Dear All, Hope all you fine. Right now I am stuck in the middle of the thermal load calculation. I am making this calculation for the vehicle workshop. There we are making ventilation and cooling by the 100% FAHU. I gave all the space inputs and system input other than the heat gain from the...

    Pressure Drop/Head Loss calculation

    I think. dP = (K-factor)*(Fluid Density)*(square of fluid velocity)/2 this formula also for calculating pressure drop in the straight pipe. since here we do not consider any data related to the bend or variation in the cross section of the fittings. waiting for the reply

    Duct Isometric chart

    My dears.. here.. Can anyone explain me what is Duct Isometric chart? I am new to this field/ I know Psychrometric chart. but this is I received from the consultant. they want this.

    Pump head calulation

    pls, apology me to ask the question which is asked many times. but here I have some confusion.. That, for the pump head calculation of the closed loop system (Chilled Water System), here we need to consider only the friction losses not any other like velocity and static. and finally the...

    Theory behind the Flowing fluid inside the pipe

    Thanks Mr.Ashtree, But I am not asking pressure loss due to friction inside the pipe. This I can find using the Pipe sizer and some other formule. what I want is the pressure developed due to the motion of the fluid (Velocity). that is I found now that is Velocity head = V2/2g. is this correct?

    Theory behind the Flowing fluid inside the pipe

    pls, apology me to ask this kind of basic questions. iam confused my self again.. When the water flowing inside the pipe what will be the pressure exerted by the flowing fluid? I have known values of Size of the pipe, volumetric flow rate and Velocity of the fluid. by using these values can I...

    controlling humidity and temperature

    it's all about the Outside and inside condition of the system. If you want to understand clearly just take a psychrometric chart and make the outside and inside points and make a process. then you will know wheater you need humidification or dehumidification to bring the desired RH % for that temp.
