The diameter of the discharge and suction pipe of a boiler feed pump is 4 inches and 6 inches, respectively. The water delivered is 250 GPM and the temperature is 60 F. The discharge pressure near the pump is 90 psig and the suction is 12 in.hg vacuum. Find the total dynamic head if the discharge gage is located 3 ft above pump centerline and the vacuum gage connection to the suction pipe is 2 feet below the center of the pump. Assume that the head necessary to overcome the frictional resistance through the pump is 2.20 feet.

Drag measurements were taken for a 5 cm diameter sphere in water at 20 °C to predict the drag force of a 1 m diameter balloon rising in air with standard temperature and pressure. Given kinematic viscosity of water (v) = 1.0 X 10^-6 m²/s and kinematic viscosity of air (v) = 1.46 X 10^-5 m²/s.

1. Perform the Buckingham Pi theorem to generate a relationship for F_D as a function of the independent variables. Assume the drag F_D is a function of diameter (d), velocity (V), fluid density (ρ) and kinematic viscosity (v)

A steel ruler (100 mm) is used for measuring the length of a block. The ambient temperature is found likely to vary in between 24 °C and 25 °C. The temperature is likely to be anywhere within these limits. The temperature variation follows square distribution, with expected value to be 24.5 °C. Determine the degree of uncertainty that will be registered when measurement is done using steel scale? CTE = 11.5 x 10-6 / °C

A steam turbine receives superheated steam at 18.0 kg/s, 500.°C, and 3.00 MPa and exhausts it to 10 kPa with a quality of 96%. If the turbine is assumed to be internally reversible, determine the rate of heat loss from the turbine surface if the power output is 20.MW The surface temperature of the turbine is uniform at 350.°C, and the local environment (ground state) is taken to be saturated liquid water at T0 = 20.0°C.

A feedwater heater is a device to heat the feedwater before it goes into the boiler. This device receives one stream of saturated vapor at 0.8 MPa and another stream of compressed liquid at 0.8 MPa and 60 oC. These two streams combined to become saturated liquid at 0.8 MPa at the exit of the feedwater heater. The mass flow rate of the compressed liquid is 100 kg/s. Determine a) the mass flow rate of the saturated vapor, b) the exergy destroyed in the feedwater heater (To=300K, Po=0.1 MPa) (10)

A batter stands at home plate in Yankee Stadium and hits the ball toward the right field foul pole. The pole is 314 ft from home plate. If the baseball leaves the bat at a speed of 100 mph and an angle of 17.5 degrees upward, how high would the right fielders glove have to be to catch the ball before it hits the foul pole. Neglect air drag.
