How long to brute force a salted SHA-512 hash? (salt provided)

Here is an algorithm in Java:

public String getHash(String password, String salt) throws Exception {
    String input = password + salt;
    MessageDigest md = MessageDigest.getInstance(SHA-512);
    byte[] out = md.digest(input.getBytes());
    return HexEncoder.toHex(out);
}

Assume the salt is known. I want to know the time to brute force for when the password is a dictionary word and also when it is not a dictionary word.
