A worker is pressure washing a deck 4.7 meters above an alligator pond. The pressure washer produces 10 liter per minute steam of water through a nozzle with a diameter of 2.5 millimeters. A 12V battery supplies power to an electronically powered centrifugal pump that draws water from a pond. Assuming a 50% efficient system, what is the amount of electrical current that the battery must supply?

Steam is supplied to a two-stage turbine at 48 bar and 400 °C. It expands in the first turbine until it is just dry saturated, then it is re-heated to 400 °C and expanded through the second-stage turbine. The condenser pressure is 0.04 bar. High-P turbine Low-P turbine Reheater Boiler P4 = P3 = Prcheat Condenser 一 What is the formula number according to file 2 to find thespecific heat inputof the system?

What is the explanation for the stability of size in gasoline and diesel engines?

Please do parts A, B and C

) You are required to design a power plant to produce electricity. It is expected to operate at steam pressure of 10 MPa, and steam temperature between 480°C and 490°C. The condenser pressure is expected to be between 8 to 10 kPa. A reheater is also being considered after first stage of turbine where steam pressure is between 0.6 and 0.8 MPa. The steam will be reheated between 470°C and 480°C and then returned to the second stage of the turbine. Select the data from above, draw Layout and T-s diagram and Analyze a. the thermal efficiency of the plant b. the cooling water requirement in kg/s per kg/s of steam, if cooling water enters the condenser at 25°C and exits at 40°C.

Describe the components of a steam power plant and demonstrate the process of it undergoes.

A) The volumetric efficiency of a six-cylinder, 3-liter SI engine operates on a four-stroke cycle at 2500 RPM is ny = 0.91. At this condition, the mechanical efficiency of the engine is 65%, and 1000J of indicated work are produced each cycle in each cylinder. Calculate (i) Air flow rate into engine (ii) Brake output per displacement (iii) Torque.
