Note: Use three decimal places and no need to input the unit. Consider a river flowing toward a lake at an average velocity of 3 m/s at a rate of 500 m3/s at a location 90 m above the lake surface. Determine the power generation potential of the entire river at that location.  (in MW)

A 150-mm-diameter jet of water is discharging from a nozzle into the air at a velocity of 45 m/s. Find the power in the jet with respect to a datum at the jet.

A Francis turbine of diameter 3.0 m develops 6750 kW at 300 rpm under a net head of 45 m. A geometrically similar model of scale ratio 1: 8 is to be tested at a head of 9 m. Estimate the size, speed discharge and power developed by the model. What is the specific speed of the model? (Assume overall efficiency of 0.82 for both the prototype and model)

A certain brand of hotdog cooker works by applying a potential difference of 146 V across opposite ends of a hot dog and allowing it to cook by means of the thermal energy produced. The current is 12.8 A, and the energy required to cook one hot dog is 60.8 kJ. If the rate at which energy is supplied is unchanged, how long will it take to cook three hot dogs simultaneously?

1. An unknown lamp placed 6m from a photometer screen provides the same illuminance as a 90 cd lamp placed 4 m from the screen.  What is the candlepower of the unknown lamp? 2. The illuminance of a room 20 ft x 15 ft is being designed.  The illuminance required is 50 footcandles.  What is the total required lumens output of the lamp assuming room and luminaire efficiency of 42%?

Problem 3 Water (20°C) is pumped through the 300-mm steel pipe from the lower tank to the upper one at a rate of 0.4 m³/s. Given that the pump efficiency is 65% and the pump is on for 5 hours each day, what will be the monthly (30 days) energy cost for the pump if the electricity rate is 0.5 USD per kWh? Assume α = 1.0 throughout. Elevation=235 m 10 m 50 m Elevation 200 m = 300 mm r = 300 mm 100 m

A generating system consists of the following units:(A) 1 x 10 MW unit(B) 1 x 20 MW unit(C) 1 x 30 MW unit(D) 1 x 40 MW unitThe 10, 20 and 30 MW units have forced outage rates of0.08. The 40 MW unit has afull forced outage rate of0.08 and a 50% derated state which has a probability of0.06. (a) Calculate the LOLE for this system for a single daily peak load of 60 MW. (b) Whatis the LOLE for the same condition if the 40 MW unit is represented as a two-statemodel using an Equivalent Forced Outage Rate?

One single phase energy meter operating on 230 V and 5 A for 5 hours makes 1940 revolutions. Meter constant in revolution is 400. The power factor of the load will be:

↑ 95 m V₁ Türbin 500 The water taken from a stream at an average speed of 5 m/s is transferred to the turbine with a pressure pipe system in order to generate electrical energy. The flow rate of 10 m3/s passing through the pressure pipe is poured into the lake on the downstream side after passing through the turbine. The total irreversible energy loss between points 1 and 2 is determined as 8 m. Calculate the theoretical and actual power of the turbine by taking the efficiency of the turbine- generator group, n = 0.85
