  • Getting Cold Water when Warm or Hot was Selected - Product

    The same is true for people living in a hot region. The tap water may be warmer than normal and so if you request a warm wash the unit may never make a request for hot water since the water entering the appliance will be at the proper wash temperature coming out of the water line.

    indication of water quality. TEMPERATURE Temperature of a waterway is significant because it affects the amount of dissolved oxygen in the water. The amount of oxygen that will dissolve in water increases as temperature decreases. Water at O oC will hold up to 14.6 mg of oxygen per litre, while at 30 oC it will hold only up to 7.6 mg/L.

    Where Q is the heat load BTU/min., M is the mass flow rate of the coolant in BTU per pound per degree F, dT is the temperature drop through the radiator in degrees F, and * indicates multiplication. Since a gallon of coolant weighs about 8.3 pounds, we can replace M in the expression by 8.3 times the coolant flow in gallons per minute, or GPM.
