Water flows in a rectangular channel that is 2.2 m wide as shown in the figure below. The upstream depth is 70 mm. The water surface rises 45 mm as it passes over a portion where the channel bottom rises 15 mm. If viscous effects are negligible, what is the flowrate? Q= i m³/s 70mm 100mm 15mm

Calculate the rate of flow of waste thermal energy out of the engine in the exhaust gases in kW (to 1 decimal point). If the air inlet temperature is 35 °C, the air to fuel ratio is 10:1, the inlet air mass flow rate is 37 kg/hr, the specific heat capacity of exhaust gas is 1.13 kJ/kg/K, and the exhaust temperature is 500 °C. Add your answer Integer, decimal or E notation allowed

An electric hot water heater consumes 3.1 kilowatts of electricity and converts it to heat. How long will it take the water heater to heat a 67 gallon tank of water from 10 degrees Celsius to 50 degrees Celsius? (1 kilogram of water is 0.37 gallons, 1 Calorie = 4200 J).  It may be helpful to refer back to the weekly handout for guidance on this problem. Your final answer should be in minutes (rounded to the nearest 10 minutes).

can you provide an answer easie to read. the answer is put into sentences like fcv=mgcos 6
