Calculating Steam Consumption for Heating Curry Sauce | Heat Transfer Rate

[Carlo09]

I have a question about curry sauce. I've had to calculate heat transfer rate which was 109.6KW to heat the sauce to 98 degrees in 60 mins... also the sauce is heated by condensing steam at 105 degrees and i worked out that the pressure needed for this is 20.973kpa

Now i have to work out the rate of steam consumption to deliver the heat transfer from the first part. I'm thinking use Q=ml but how do i do this? Is m the mass of steam?

Also we are given the mass and density of the sauce... but so far i have not needed the density, could that just be there to trick us or can someone see where i may need it? Thanks

.The rate of steam consumption will be determined by the mass flow rate of steam and the enthalpy of the steam entering the system (the condensing steam at 105 degrees). You can calculate the mass flow rate using the equation: Q = m * h, where Q is the heat transfer rate, m is the mass flow rate, and h is the enthalpy of the steam. The density of the sauce is not relevant to this calculation.

Based on the information provided, it appears that the goal is to calculate the rate of steam consumption for heating curry sauce. To do this, you will need to use the equation Q=ml, where Q is the heat transfer rate, m is the mass of steam, and l is the latent heat of steam. The mass of steam can be calculated by dividing the heat transfer rate by the latent heat of steam, which can be found in a steam table. The density of the sauce may not be necessary for this calculation, as it is not directly related to the steam consumption. However, it is important to consider the density of the sauce when determining the amount of steam needed to heat a specific volume of sauce. I hope this helps clarify the process for calculating steam consumption for heating curry sauce.
